More Than Just Structural Metal Decks

Here at SMD Stockyards, we don’t just supply structural metal decking for flooring. We offer a wide range of other products for our clients, all of which are of the highest quality. In addition to floor decking, we also provide structural roof decking, along with additional products such as: 

You can find out more about all of our products by continuing to read below. 

Floor Deck

First up is our floor decking components, which are required as either part of a formwork only solution or an integral part of a structural composite slab. Here at SMD Stockyards, you will find that we stock many floor deck products for our clients, such as the R51+ Floor Deck. This is commonly used on projects throughout innercity areas, such as the construction of high, multi-storey buildings where the structural zone is limited. 

You will notice that this re-entrant profile features a relatively thin slab depth, which means it offers a fire rating of around 1 hour. This R51+ Floor Deck is available in 0.9mm, 1.0mm, and 1.2mm gauges, manufactured from S350 and S450 grade galvanised steel. There are soffit fixings available with a 1kN load capacity. 

We also provide the TR60+ Floor Deck, which offers high span capabilities and superior steel efficiency. This product can be installed quickly thanks to the 1.0m cover width, and this makes it a fantastic choice for design engineers especially. You will see it sports a 130mm slab, offering a fire rating of around 1 hour, and it is available in 0.9mm, 1.0mm, and 1.2mm gauges and manufactured from S350 and S450 grade galvanised steel, like the R51+. This product also has 1kN load capacity soffit service fixings available. 

At SMD Stockyards, we also stock the TR80+ Floor Deck, which boasts the same specifications as our above products. The difference between the three products, however, is that this one is an 80mm deep trapezoidal profile boasting un-propped span capabilities and concrete volume requirements. 

Roof Deck

At SMD Stockyards, we also supply a range of roof deck options for our clients, starting with our SR30+ Roof Deck. This is typically used as the structural deck for singleply membrane, doubleskin built up, standing seam, green roof, and asphalt systems. It has a 1.0m cover width, which helps maximise the speed of installation, and it is available in two coating options; galvanised or polyester white. This product is 30mm deep, available in 0.7mm and 0.9mm gauges and is manufactured from S350 grade steel. 

Next up is our SR35+ Roof Deck, which is again typically used as the structural deck for simple play membrane, double-skin built up, standing seam, green roof, and asphalt systems. It is also available in two coating options, galvanised or polyester white, but is 35mm deep. This roof deck is available in 0.7mm, 0.9mm, and 1.2mm gauges and manufactured from S350 grade steel. 

We also stock the SR60+ Roof Deck here, which can be used as a structural base in a number of lightweight roof and mezzanine floor solutions. It is available in the same two coatings as our other roof deck options, but you will find this product is 60mm deep. It has been manufactured using S350 grade steel and is available in 0.7mm, 0.9mm, and 1.2mm gauges. 

Finally, we have our SR100+ Floor Deck, which is used as the structural deck for simple play membrane, double-skin built up, standing seam, green roof and asphalt systems, but it is ideal for heavier roof systems than our previous products. It is available in the same coating options and is 100mm deep, manufactured from S350 grade steel, and available in 0.7mm, 0.9mm, and 1.2mm gauges. 

Shear Studs

Here at SMD Stockyards, being the number one supplier of structural metal decking means we are also your goto supplier for quality shear studs too. All of our shear studs are European in source, and they all adhere to the required British and European standards, manufactured in accordance with the requirements of BS EN ISO 13918:2008. 

The length of our shear studs, as advertised, is the length before the welding process; when welded to the base metal, they will be approximately 5mm shorter after weld, and when welded through the deck, they will be 10mm shorter after weld.  

We are also now proud to say that we are a UK accredited supplier of Nelson headed shear studs. The specifications for our shear studs have been listed below: 

  • 19mm dia x 105mm long 
  • 19mm dia x 130mm long 

Ten thousand standardsized shear studs are kept in stock daily, and we can order in other sizes on request.

Roof and Wall Cladding

Next up on our product list, we have our roof and wall cladding, which comes in a variety of options, starting with the RC30 Roof Cladding. This can be manufactured and produced in colourcoated steel (Plastisol, PVF2, and Polyester) or in plain galvanised steel or Aluzinc. This product is available in a 200-micron leather grain effect Plastisol finish, and it is 30mm deep with a 0.7mm gauge available. It has been manufactured from S350 grade galvanised steel, and we also offer colour matched flashings, trims, and box gutters too. 

Next, we have the WC30 Wall Cladding, which is manufactured and produced in colourcoated steel (Plastisol, PVF2, Polyester) or in plain galvanised steel or Aluzinc. It is available in a 200-micron leather grain effect plastisol finish and is 30mm deep with a 0.7mm gauge available. The WC30 Wall Cladding has been manufactured with S350 grade galvanised steel and has colour matched flashings, trims, and box gutters available. 

Our final product is the Sinus Roof and Wall Cladding, which is suitable for various applications such as agricultural, industrial, commercial, and domestic. It is available in Polyester colour coated steel and is 19mm deep with 0.5mm and 0.7mm gauges available. As with our other cladding products, this has been manufactured from S350 grade galvanised steel and has colour matched flashings, trims, and box gutters available too. 

Filler Blocks 

Next up on our product list is profiled filler blocks, which are a cheap and easy alternative to the conventional end caps. They are manufactured from polyethene (white) or high-density rock wool (fire-rated option).  

Our fire-rated filler blocks have been fire-rated for one hour and tested to BS 476 part 20. They are supplied in packs of 250 and are available to use with TR60+ and TR80+ deck profiles. They also feature an acoustic rating of 47dB. 

Reinforcement Mesh

At SMD Stockyards, we also stock and supply a variety of reinforcement mesh and, due to the demand, sheet reinforcement mesh is readily available from our stockyards daily. Our stock sheets measure 4.8m x 2.4m and are electrically welded to BS4483 standards. You will find they are available in the following variants: 

  • A142 
  • A193 
  • A252 
  • A393 

Edge Trim and Flashing

Two other products we offer here at SMD Stockyards are edge trims and flashings, which we will discuss separately. Edge trims can be used for permanent formwork of the slab when pouring concrete on to pre-cast or metal deck floors. You will find that forming the edge of the slab using cold rolled edge trim is the most accurate and economical method, and we have trims available in 3m lengths and various depths (depending on the slab depth). The gauge is determined by the depth of the slab, and the extent of the overhang required. 

Our flashings can be used to close small gaps to finish off bays without the need to cut a fullwidth deck sheet, which helps to reduce wastage. These are supplied in 3m lengths and, where studs are required, flashing may be required at perimeter and intermediate beams to allow the studs to be installed. 

GRP Grating

The final product we offer for our clients is GRP Grating, which is glassreinforced plastic grating used for safe and efficient void and flooring solutions. There are many benefits to utilising GRP Grating in your project, which we will talk about below. 

First, you will find that having GRP Grating installed will provide slip-resistant benefits. The gritted surface of this product provides unrivalled slipresistance when compared to other products. It is also extremely lightweight. In fact, you will find that GRP Grating is nearly half the weight of any conventional steel grating systems. This makes it easy to install and negates the need for any lifting equipment to do so. 

You will also find that our GRP Grating is corrosionresistant too, which makes it ideal for use on various building specifications and environments. This product is also non-conductive, bi-directional loadbearing, and comes with a 25-year guarantee. 

This product is commonly used for applications such as: 

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