Ancillary Products

AMDECK design and manufacture the highest grade, premium strength steel decking in the UK. Our AMDECK 54, AMDECK 60 and AMDECK 80 steel decking is widely used in the construction industry because its patented design properties and unique embossments deliver exceptional structural performance, which is unmatched in market place.

Complementing AMDECK’s range of quality composite steel decking, we also design and manufacture a range of high-quality ancillary products using premium grade materials.

For added value, our in-house design team can factor in any required steel decking ancillary products as part of your design, or we can produce and deliver ancillary items retrospectively.

Below is a range of our most popular steel decking ancillary products, however, please contact us direct if you have any questions.

Steel Decking Closure Plates


Steel decking closure plates are used when the metal deck falls short of the supporting beam. The closure plate fills the gap and prevents grout loss when the concrete is poured.  AMDECK closure plates are available in the following widths and gauges:

Steel Decking Edge Trim

Steel decking edge trim acts as permanent formwork to the edge of the slab when pouring concrete onto metal deck floors. AMDECK can manufacture all types of steel decking edge trim to any thickness that is required for your project. Our steel decking edge trim is produced using galvanised sheets, from 0.9mm to 2mm gauge and from 100mm height to 600mm height.

Steel Decking Restraint Straps

One the edge trim is fixed to the supporting beam, the upper section of the edge trim is restrained by straps at 600mm – 1000mm, depending on slab depth and overhang from the supporting beam. AMDECK manufacture steel decking restraint straps from 0.7mm galvanised sheets.

Steel Decking End Cap

Steel decking end caps are required on AMDECK 60 and AMDECK 80 trapezoidal profiles in order to prevent grout loss whilst the concrete is poured. AMDECK manufacture universal end caps from 0.7mm galvanised sheets.

As always, our technical team is always on hand to advise you and your team, and our design team can also produce drawings that include both composite steel decking and any require steel decking ancillary products.
