The obvious benefits of structural roof deck profiles are well known to most persons working in the construction industry. If you’re still not convinced, we’ve summarised these advantages for you below. The following are the details:

  • Rapid Construction Speed 
  • Excellent Tensile Reinforcements 
  • Reduced Steelwork Frame Weight
  • Reduced Foundation Costs 
  • Integral Ceiling and Service Fixing Systems 
  • Permanent Shuttering 
  • Coverage for Following Trades 
  • Provides Safe Working Platform (when fixed) 
  • Minimal Site Storage Requirements 
  • Easily Incorporated into Complex Designs 
  • Fire Rating Up to Four Hours 

So, how does it all come together? Because structural roof decking may be built quickly, your entire project time will be decreased. You can achieve the same tensile reinforcing requirements of the slab while decreasing the steelwork frame weight by using a structural roof deck profile. Reduced loading correlates to cheaper foundation expenses, which has a significant impact on the structure’s foundations.

After the deck profiles have been installed, they can be used as permanent shuttering while also providing protection for subsequent trades, such as anyone who needs to operate on roofs after the profiles have been installed. The benefit of structural deck profiles is that they take up very little room. You can order them in advance and save them until you’re ready to utilise them.

What about the design, though? Some roofs are more difficult to maintain than others. That’s great, because structural deck profiles are simple to incorporate into complex designs while reducing waste. This will help you save money. Finally, deck profiles provide extra safety benefits due to the slab’s high fire rating of up to four hours.


SMD Stockyards is without a doubt the UK’s largest and most recognised stockist and supplier of high-quality structural decking. We stand out from the competition with our extensive line of metal floor and roof structural deck components. You may have looked elsewhere and been disappointed in not being able to discover exactly what you’re looking for. When you choose us, though, you will not be disappointed.

We truly have the largest collection of structural roof deck products, with solutions to fit any building size from small to medium to large. Simply let us know if you’re not sure which of our goods will best suit your project needs. We’d be more than glad to discuss your requirements and recommend the best product for you, ensuring that you receive the results you want. We also provide a full yard service, which you can learn more about further down.

However, before you go any further, you might want to take a look at some of our products. If that is the case, you have arrived at the correct article. From floor and roof deck components to cladding, filler blocks, edge trims and flashings, and GRP grating, we’ve listed the details of some of our fantastic goods below. The following information should give you a better idea of what to expect when shopping at SMD Stockyards.

Floor Deck

Let’s start with our vast selection of floor deck components. Whether as part of a formwork-only solution or as an integral part of a structural composite slab, these components are necessary. We have numerous good floor deck items in stock at SMD Stockyards, starting with the R51+ Floor Deck.

The R51+ Floor Deck is a popular floor deck profile that is often employed in inner-city regions. Its most prevalent use is in the construction of high multi-story buildings with a limited structural zone. This re-entrant profile has a relatively thin slab depth, which means it has a one-hour fire rating.

The R51+ Floor Deck is made of S350 and S450 grade galvanised steel and comes in 0.9mm, 1.0mm, and 1.2mm gauges. Soffit service fittings with a 1kN load capacity are offered.

The TR60+ Floor Deck comes next, with high-span capabilities and improved steel efficiency; thanks to its 1.0m cover width, this cost-effective structural solution can be constructed rapidly. This makes it an ideal alternative for design engineers in particular. It has a 130mm slab, which means it can withstand a one-hour fire. The TR60+ Floor Deck is made of S350 and S450 grade galvanised steel and comes in 0.9mm, 1.0mm, and 1.2mm gauges. Soffit service fittings with a 1kN load capacity are available, just like the R51+.

You should also think about the TR80+ Floor Deck, which has the same features as the other two alternatives. The TR80+ is distinguished by its 80mm deep trapezoidal profile, which offers exceptional unpropped span capabilities and concrete volume needs. This option is highly recommended if your project could benefit from such specifics.

Roof and Wall Cladding

Following that, we’ll go over our roof and wall cladding alternatives, which are meant to complement our fantastic decking selections. If you’re working on a project that requires structural profiles and cladding, such as RC30 Roof Cladding, you’ll discover some terrific possibilities below.

Colour-coated steel (Plastisol, PVF2, and polyester) is standard on RC30 Roof Cladding. Alternative Aluzinc and galvanised steel types are also available to meet your needs. RC30 Roof Cladding is offered with a plastisol finish and a 200-micron leather grain look. It’s 30mm deep, has a 0.7mm gauge, and is made of S350 galvanised steel. Flashings, trimmings, and box gutters in a variety of colours are available, and they’re all custom-made in-house in conventional 3m lengths.

Is there something else you’re looking for? Then look no further than our WC30 Wall Cladding. This option, like the RC30, is available in colour-coated steel (Plastisol, PVF2, and polyester) as standard, as well as Aluzinc and plain galvanised steel. This option has the same specs as the RC30 Roof Cladding, including a 0.7mm gauge, 30mm depth, and a 200-micron leather grain effect with plastisol finish.

Consider the Sinus Roof & Wall Cladding system, which is suited for a wide range of applications, including industrial, commercial, residential, and even agricultural settings. This polyester colour-coated steel option is 19mm in depth, comes in 0.5mm and 0.7mm gauges, and is made from S350 grade galvanised steel. Colour-matched flashings, trims, and box gutters are also available, as are the other alternatives.

Shear Studs

SMD Stockyards is the go-to company for top-quality shear studs in addition to being the top supplier of structural decking. These are essential for attaching items to the structure of a home.

The fact that all of our shear studs are obtained from Europe is the major reason you should come to us for shear studs. Any studs created in Europe must meet all current British and European standards, therefore this is a hallmark of quality. These requirements are stringent, so you can be confident in the studs you’re purchasing. All of the studs we sell are made in accordance with the BS EN ISO 13918:2008 standards.

Our shear studs have a diameter of 19mm and a length of 105mm or 130mm (length). We stock 10,000 standard size shear studs on a daily basis, so you’ll never be without what you need. If you require different sizes, we can produce them for you. Please keep in mind that the length listed for our shear studs is the length BEFORE any welding. Shear studs will be roughly 5mm shorter after welding. They’ll be 10mm shorter when welded through a deck.

SMD Stockyards is a UK authorised provider of Nelson headed shear studs, so make sure to come see us!

Filler Blocks

Look no further than SMD Stockyards if you’re seeking the best filler blocks and fire-rated filler blocks. We have the highest-quality filler blocks on the market, so you won’t have to look elsewhere.

Filler blocks are a popular choice among builders all over the world as a low-cost, simple, yet effective alternative to traditional end caps. The ones we sell are made of white polyethene or high-density Rockwool (fire-rated option). We use the best high-density Rockwool stone wool for the fire-rated blocks to achieve a one-hour fire rating.

These filler blocks have been tested to BS 476 part 20, come in packs of 250, and have a 47dB acoustic rating that can also be used with the TR60+ and TR80+ floor decking profiles.

Reinforcement Mesh

Do you happen to have a need for structural reinforcing mesh? If that is the case, you’ve come to the right place because we have the greatest range of options available. Because reinforcement mesh is in great demand, we’ve ensured that our processes are scalable enough to meet said demand. So, when you come to our stockyard, you can expect to discover a plentiful supply, ensuring that you have just what you need to do the job.

Our stock sheets are 4.8m x 2.4m in size, electrically welded to BS4483 specifications, and come in the following options:

  • A142 
  • A193 
  • A252 
  • A393 

Edge Trim and Flashings

When pouring concrete onto metal or pre-cast deck flooring, edge trims and flashings are a common element utilised to create the slab’s permanent formwork. As a result, you’ll want to make sure you’re getting the best edge trims and flashings money can buy. You’ve already made a great decision by coming to SMD Stockyards.

Our edge trims are high-quality and provide a cost-effective and precise solution. The slab’s edge is usually formed with cold-rolled edge trimmings. The trims are approximately three metres long and come in a variety of depths to suit the slab depth. There are a variety of gauges to choose from depending on the slab depth and the amount of overhang necessary.

When it comes to flashings, these can be utilised to fill in small gaps when completing bays. It’s unnecessary to cut a full-width deck sheet. As a result, waste and total expenditures are reduced. Our flashings are available in three-meter lengths. When studs are required for perimeter and intermediate beams, flashing may be required. This makes it possible to insert the studs.

GRP Grating

Glass-reinforced plastic, or GRP, is a form of fibreglass material that is frequently used as a fire retardant. It’s non-conductive and lightweight, making it ideal for use in industrial constructions that require such characteristics. It’s also used for a variety of other purposes, including: 

  • Fire Escapes 
  • Raised Floors 
  • Platforms 
  • Drain Covers 
  • Protective Shields 
  • Stair Treads 
  • Walkways and More

So, if you’re looking for a quick, safe, and effective void and flooring solution, go no further than SMD Stockyards’ GRP grating.

GRP grating has numerous advantages that make it a worthy addition to any construction project. For starters, the gritty surface makes it slip-resistant, making it extremely safe to walk on. Because it provides excellent traction, it’s widely used for stair treads and walkways. It’s also light — GRP grating systems are around half the weight of traditional steel grating systems. This not only makes installation easier because no lifting equipment is required, but it also reduces overall loading.

GRP grating may be employed in a wide range of architectural standards and settings because to its exceptional corrosion resistance. GRP grating also eliminates the requirement for traditional handrails since it provides adequate void protection. We have GRP grating in stock that has a 25-year warranty, is load-bearing in both directions, and, as previously indicated, is non-conductive.

The GRP19TM, which is 38mm deep, weighs only 96kg per panel (21.5kg per square metre), and measures 3660 x 1220 per sheet size, is one of the items available. There’s also the GRP38TM, which is 38mm deep as well. This option is available in green, red, and yellow and weighs only 83kg per panel (18.6kg per square metre).

Finally, there’s the GRP50TM, which is 50mm thick, weights 105kg per panel (23.5kg per square metre), and is available in the same sheet size as the other two alternatives.

Service Fixings and Consumables

If we didn’t carry and supply a wide range of service fittings and consumables, we wouldn’t be the go-to firm for high-quality structural metal and roof decking profiles.

Service fixes for aligning cable trays and pipework are among the materials we keep on hand. R51, TR60+, and TR80+ systems can all benefit from these fittings. 6mm, 8mm, and 10mm rods are among the options. Hilti X-U General-Purpose Nails and Cartridges are another item we carry. These nails and cartridges can be used to secure deck and edge trim to steelwork, but they require the Hilti DX 460 tool to do it.

We also have Hilti S-MD Tek Screws in stock, which are used to side-stitch deck sheets and secure restraint straps to edge trims. We propose our Metal Cutting Discs if you need a petrol-powered disc cutter. We also recommend our Expanding Foam and Silver Tape for sealing around columns and decking butt joints to minimise grout loss. Finally, we have Roof & Cladding Screws that are now available in stock with coloured caps.
