7 Best Garage Shelving Units (2021 Review)

The best garage shelving units should be robust and sturdy enough to support surprisingly large loads. Steel framed units should have individual shelves that can support well over 150kg in weight. It goes without saying that both frames and shelves should be weatherproof.

A lot of shelving units can be linked together and sometimes individual units can be split into two and double as a work surface. Units should feature shelf height adjustment and look for a central support bar with heavy duty shelving. Most shelving systems come in a flat pack and do not require tools for assembly – they either come with metal tabs and holders or with keyholes and pegs. Either way you can easily put shelving units together on your own.

I’ve heavily researched all the best shelving systems available right now, so read on and see what I’ve found out…

G-Rack Blue 5 Tier Garage Shed Storage Shelving Units review

Specifications

  • Type: Heavy Duty
  • Shelves per Unit: 5
  • Unit Dimensions: 180x90x40cm
  • Frame: Stainless Steel
  • Shelf Capacity: 175kg
  • Shelf Height Adjustment: Yes
  • Unit Splits into 2: Yes

G-Rack are the experts in storage and shelving solutions. Their 5 tier garage storage unit is a seriously handy rack for use in the garage, workshop, or anywhere where you need to stow stuff away.

They’ve designed a sturdy powder coated steel frame that holds five tiers of 5 mm MDF shelves. It’s not too taxing to put together, but only if you start at the bottom and work your way up. G-Rack use the metal tab system for holding everything in place, so you don’t need to mess around with bolts or screws.

What I like about this unit is you can split it into two if you want. Set up as the tall unit it’s 180 cm high, and as the lower unit it’s 90 cm high. Both units are 90 cm wide and 40 cm deep. The shelves themselves are made from 5 mm thick moisture resistant MDF. Each unit is rated to hold a total weight of 175 kg.

I think it’s one of the best shelving units around if you are looking for heavy duty garage shelving on a budget.

Pros

  • Don’t worry about it not being delivered with enough nuts and bolts. Everything slots together with metal tabs and holders. It doesn’t look strong, but it is!
  • The large shelf deck sizes are ideal for when you need that bit more space. At 90 cm wide and 40 cm deep, they’re huge compared with the Amazon Basics shelves.
  • You can split the shelves into two units if you want. It makes it a wonderfully versatile system depending on the shape of your shed or garage.
  • The 5 mm thick MDF is thick enough to be rigid. Anything thinner than that might warp or bend. It’s weather resistant as well, so it shouldn’t swell up in a damp shed.
  • The total capacity of 875 kg is incredible for such a portable unit. You could store almost anything you want across the shelves!

Cons

  • Make sure you have a flat head screwdriver and a rubber mallet to hand when you put it together. The tabs have a habit of not seating properly in the holders. They get there eventually.
  • Some users have had issues with the MDF shelves. Even though they say they’re weather resistant, they have become mouldy in damp sheds. This can lead to bowing.
  • The feet are made from a rigid plastic, not rubber as you’d expect. It’s hard getting them onto the ends of the legs, and they fall off too easily.
  • Some users have notices that the paint can be too thick on some of the tabs, making them hard to insert into the slots. Once they’re in, they’re hard to adjust.

Storage Affairs Heavy Duty Garage Shelving review

Specifications

  • Type: Extra Heavy Duty
  • Shelves per Unit: 5
  • Unit Dimensions: 176x90x45cm
  • Frame: Steel
  • Shelf Capacity: 265kg
  • Shelf Height Adjustment: Yes
  • Unit Splits into 2: Yes

Based in Stratford-upon-Avon, it’s no secret that Storage Affairs know a thing or two about the best heavy duty shelving unit. Their frankly enormous rack system is ideal for hiding away big bits and pieces in your workshop, garage or shed.

Making use of chipboard shelf decks rather than MDF, each one can hold heavier weights than you might first think. Making use of a powder coated steel frame, the whole thing is rigid and reliable, and thankfully corrosion resistant.

The unit is 180 cm high, 90 cm wide and 45 cm deep. The five heavy duty MDF shelves can be adjusted to suit your storage requirements. The shelves come with connectors so you can join units together to create sturdy garage wall storage. The MDF has been tested to hold a maximum evenly distributed weight of 265 kg.

You can adjust the shelves wherever you need them because the connecter clips are just 35 mm apart. I like that because shelves like these are often quite inflexible. There are no nuts and bolts to lose, thanks to the tab and slot system.

Pros

  • The 8 mm thick shelves are mighty. Made from sturdy chipboard, they’re stronger than the ones on the G-Rack and should last longer too.
  • The individual shelf capacity of 265 kg is immense. They’re strong enough to hold tools, tins of paint, heavy books, or whatever you need to store.
  • The metal frame is made from 1.2 mm thick stainless steel. It’s not flimsy and makes the whole shelf system feel seriously sturdy.
  • At 90 cm wide and 45 cm deep, you can fit a lot of stuff on each shelf. They’re deep enough for the biggest items and boxes. They’re much larger than “standard” shelf sizes.
  • The fact that you can join them together makes them incredibly sturdy. As long as you’ve got the room, and you attach them to a wall, they’ll hold anything you like.

Cons

  • They’re a fair bit more expensive than the G-Rack shelves. If you’re on a budget, then they’re probably not going to be your fist choice.
  • Just like the G-Rack, you’ll need to persuade some of the tabs into the slots. Having a rubber mallet on hand is a good idea during assembly.
  • Fitting the middle support sections involves a bit of lateral thinking. You’ll need to bend the end tabs too far until they stay in place. It’s hard to do the first couple.
  • Some users have complained about mould growing on the shelves. You should treat the shelf decks with preservative, and make sure your shed or garage has adequate ventilation.

Amazon Basics 3-Shelf Shelving Unit review

Specifications

  • Type: Heavy Duty
  • Shelves per Unit: 5
  • Unit Dimensions: 183x91x36cm
  • Frame: Steel
  • Shelf Capacity: 160kg
  • Shelf Height Adjustment: Yes
  • Unit Splits into 2: No

The Amazon Basics range contains an incredibly diverse collection of tools, technology, and homewares. If you’re looking for a no-frills, sturdy shelving set, their 3-shelf shelving unit is just the ticket.

The shelves are made from sturdy steel with a black coated chrome finish. You don’t need to worry about mouldy or bowing MDF shelf decks either. The whole thing is wire racking welded firmly together on each level.

The 3 wire shelves can each hold nearly 115 kg in weight. The shelves can be adjusted higher or lower without tools in 1″ (2.54 cm) increments. As well as this 3 shelf unit, you can get 2, 4 or 5 shelf versions to fit the space you have.

Standing at 59 cm tall, it’s ideal as a low rack rather than a tall set of shelves. The depth and width of each shelf is a reasonable 34 cm deep and 76 cm wide. They’re big enough to hold plenty of items but small enough to fit into tight spaces.

What I really like about these budget shelves are the adjustable feet. If your floor is a bit uneven, you can change the height of each leg enough to compensate. Handy!

Pros

  • This is a serious bargain for what you get. Sturdy steel frame and wire shelves for not a lot of money. They’re available in all sorts of sizes as well.
  • They might be the Basics brand, but they’re far from basic looking. They have an industrial look, rather than utilitarian shelving like the G-Rack.
  • This is another shelving unit that doesn’t need any tools for assembly. And compared to the G-Rack shelves, you don’t even need a mallet and screwdriver.
  • The two part sleeves that hold the shelves up are a clever design. You can adjust them easily and they’re surprisingly strong too.

Cons

  • Several users have complained about the poor instructions included. They don’t seem to be much help at all for putting them together!
  • The clips are a clever design but can be confusing. Several users have complained that they seem “upside down”. The top is marked, but if you miss it, you won’t put the shelf up right.
  • Unless you make sure to stack things in weight order: heavy at the bottom and light at the top, it’s a wobbly set of shelves.
  • It’s a shame that the top of the legs isn’t threaded so you can join multiple units together. The central joint is threaded, so I think Amazon have missed a trick here.

TAHA Heavy Duty Boltless Metal Shelving review

Specifications

  • Type: Heavy Duty
  • Shelves per Unit: 4
  • Unit Dimensions: 150x75x30cm
  • Frame: Alloy Steel
  • Shelf Capacity: 175kg
  • Shelf Height Adjustment: Yes
  • Unit Splits into 2: No

With an interesting line of shelving, TV mounts and other useful stuff, TAHA know all about heavy duty shelving. Their heavy duty boltless metal shelving unit is strong, sturdy and a bit of a bargain.

The alloy steel frame might look thin, but once it’s slotted together it’s surprisingly strong. Each MDF shelf is 5 mm thick and rated to hold up 175 kg. Each deck has a footprint of 73 cm wide and 30 cm deep. The shelving unit itself raises up to 150 cm.

This industrial looking set of shelves is galvanised rather than powder coated, so it should be incredibly weather resistant. It also makes it look rather good if you ask me.

TAHA make use of the tried and tested tab and slot fastening mechanism. You don’t need much in the way of tools or DIY knowhow to put this set together, just a bit of patience. The finish on the galvanising can be a bit rough in places. If you’re careful during assembly this is still one of the best budget shelving units available.

Pros

  • The galvanised alloy steel frame should be hard wearing. It’s a process designed to protect against corrosion, so it should be fine in your shed.
  • The assembly is relatively straightforward. Once you’ve figured out the tab and slot system, it goes up easily. All you need is a rubber mallet and a flathead screwdriver to guide some in.
  • TAHA have included a pair of safety gloves with the shelves. They should keep your hands safe when putting up the shelves.
  • You can adjust the height and spacing of the shelves when assembling the unit. You can pick the tabs that suit your items and fit them where they’re needed.

Cons

  • Several users have complained about sharp edges on the frame. You’ll need the included safety gloves to keep your hands out of trouble.
  • It’s not as tall compared with the G-Rack system. The shelves can’t hold as much either.
  • Some users have had issues with mould growing on the MDF shelves. This can be an issue in damp sheds with poor ventilation. You should seal the shelf decks before assembly.
  • You’ll need to assemble the shelves where they are needed. Moving them once they’re up can be difficult.

VonHaus 4 Tier Plastic Shelving Unit 2 Pack review

Specifications

  • Type: Light Duty
  • Shelves per Unit: 4
  • Unit Dimensions: 133x60x30cm
  • Frame: Polypropylene
  • Shelf Capacity: 20kg
  • Shelf Height Adjustment: No
  • Unit Splits into 2: No

Those clever DIY manufacturers from Manchester, VonHaus, make plenty of useful bits of kit for the home and garden. Their take on a light duty storage solution is made from tough plastic. Don’t be put off, it can still hold a decent amount of stuff without any problems.

First off, one of the best things about this shelving set is that you get two separate racks. There are some real benefits to plastic shelving too. One of the main complaints about wood or MDF shelves in damp sheds is mould. Plastic shelving doesn’t have that issue, and these are protected from UV damage as well.

These shelves are made from weatherproof, anti-shock polypropylene, so there’s no brittle plastics here. Manufactured in Italy, you can be guaranteed a decent quality control process as well. Putting the shelves together is incredibly simple as well and can be completed in just a few minutes.

Each shelving unit is 132 cm tall, and the shelf decks are 60 cm wide and 30 cm deep. They’re not the biggest on my list, but sometimes you need them to fit a tighter space anyway. Each shelf is rated for just 20 kg, but when you add it all together you can still stow away plenty of gear between the two units.

Pros

  • The tough polypropylene shelves are truly weather-resistant. You don’t need to worry about mould, rot or fungus growing on them in a damp garage.
  • They come with wall brackets to keep them from toppling forward. These are vital if your floors aren’t level or if you have children around.
  • If you’ve been put off trying to put together shelving with the tab and slot system, the VonHaus is ideal. Simply push the legs into the holes and you’re good to go.
  • Even though they’re easy to put together, VonHaus include detailed instructions. Compared with the useless ones supplied with the TAHA set, it’s good to see.

Cons

  • Compared with the Storage Affairs shelving unit, this is a weak set of shelves. A single Storage Affairs shelf is rated to hold more weight than both the VonHaus shelves combined!
  • You can’t adjust the height of the individual shelves. In comparison with the TAHA shelves, you’re limited to what VonHaus have set out – 45 cm.
  • At just 133 cm tall, these aren’t quite tall enough compared with the G-Rack shelving units. The shelves aren’t particularly big either if you need to store a lot of things.
  • You need to be gentle with the joints when putting them together. Use some silicone based lubricant if they’re stuck and don’t use too much force. They will break.

STORALEX Garage Shelving Rack Units Set of 3 review

Specifications

  • Type: Heavy Duty
  • Shelves per Unit: 5
  • Unit Dimensions: 180x90x60cm
  • Frame: Steel
  • Shelf Capacity: 200kg
  • Shelf Height Adjustment: Yes
  • Unit Splits into 2: Yes

Specialist shelving outfit STORALEX have put together the ultimate heavy duty set of garage racks. If you need to store lots of heavy items, this is the solution you need. Rated to hold a massive 1000 kg across the whole bay, you could use their garage shelving rack to store just about anything in your garage or workshop.

Everything about this storage system is heavy duty. The steel frame is thick, and STORALEX have opted for 6 mm rather than 5 mm MDF boards for extra sturdiness. The grey painted frame should keep them weather resistant if your ventilation isn’t that great either.

This mega storage rack makes use of the tab and slot system, so you don’t need lots of special tools to put it all together. Each shelf can be adjusted to match the height you need, and they measure a whopping 60 cm deep and 90 cm wide. That’s more than enough for most storage needs.

The overall height of the racks is 180 cm, and you can stow up to 200 kg per shelf. That’s a lot of storage capacity for any shed when you remember you get three of these big units!

Pros

  • If you’ve got a lot of stuff to store, and you’ve got a lot of space, this is the best heavy duty garage shelving solution. Compared to the G-Rack, you can store an incredible amount.
  • Compared to the rest of the storage units on my list, this can hold the most weight combined. 1000 kg is a serious maximum capacity, and it’ll take a while to fill up.
  • The shelf decks are bigger compared to the Storage Affairs ones. The 60 cm deep shelves are enormous and the biggest on my list.
  • For the size and seeing as you get a pack of three shelves, this is a good value shelving set. If you have a lot of items to store, you can’t beat these units.

Cons

  • The steel frame is painted grey. It’s probably durable enough, but it’s not as strong as galvanised or powder coated steel.
  • Some users have complained that the shelves are difficult to put together. The tab and slot system can be a pain, especially when the frames are large like these ones.
  • You need to bend the tabs that hold the crossmembers in place yourself. If you’re not careful you can crack the paint and leave the bare steel vulnerable to corrosion.
  • Some users have complained about the amount of wobble when fully loaded.

      Things to Know Before Buying Garage Shelving

      Construction Material

      Shelving units that are suitable for storing heavy items in your garage or workshop need to be made of strong materials. Usually garage shelving and workshop shelving have a thick metal frame to support the weight. This frame is usually coated to provide protection against corrosion and rust and helps the shelving unit stay strong and look good for many years.

      Garage rack systems are usually made from thick MDF that will not sag or bend under heavy weights. Some use a moisture resistant MDF. If your choice of garage shelving unit does not, it may be worth protecting the garage shelves themselves with a good waterproof finish if there is a danger of them getting wet.

      Some garage shelving units have reinforced wire shelves and these look smart enough for any room in the home. This type of wire shelf makes handy extra storage in a kitchen, utility room or playroom.

      These types of shelves are designed with wide bases to make them stable. However, you should always fix shelving units to the wall to prevent them toppling. This is particularly important if you are storing weighty items or if children might have access to the shelves.

      You should take care to spread the weight evenly over the shelves and store the heaviest items on the lowest shelves.

      Many garage storage shelves l have adjustable or non-slip feet to increase stability.

      Shelf Dimensions

      Most garage wall shelving comes in a range of sizes and the shelf units are adjustable so you can tailor the shelving units to your particular storage requirements. In addition, many garage storage shelves have a modular design. This means they can be constructed either as a tall shelf or a lower, wide bench. Many garage shelving units also come with connectors so you can clip several together to provide sturdy garage wall shelving and storage.

      Assembling the Shelves

      Most garage storage units are easy to assemble as they have a bolt free design so you don’t need any tools for assembly. However, you may find that a large flat head screwdriver and rubber mallet will be necessary to knock everything home securely. Often two people are needed to assemble the unit. Don’t forget to fix the shelves together as close to their final location as possible as the shelving units will be bulky and heavy once assembled.
