Heavy-Duty Roofing Insulation Fasteners are selected when an assembly calls for fixing steelwork, plant and services to concrete and masonry, where the anchor is set in a drilled hole and its capacity is governed by the base material rather than by the steel. This application guide to the Trade series (roof insulation fasteners and plates) type covers concrete end-uses, the specification checklist, correct installation, and where an alternative fastener performs better.
Typical Applications for Heavy-Duty Roofing Insulation Fasteners
The most common settings where these are specified:
- General machine building: fastening covers, brackets, motors and sub-assemblies on production equipment.
- Maintenance & repair (MRO): a stocked size for servicing existing plant where the original fastener spec must be matched.
- Fabrication & metalwork: bench and on-site assembly of steel frames, enclosures and weldments.
- Structural fixing to concrete: base plates, brackets, rails and steelwork bolted to a concrete slab or wall.
- Building services: suspending cable tray, ductwork, sprinkler pipe and unistrut from a soffit.
How to Specify Heavy-Duty Roofing Insulation Fasteners for Your Application
- Size: Match the size to the mating part — see the dimension table below for each option.
- Material: Choose the material and finish for the service environment — plated steel for general use, stainless for corrosion resistance.
- Environment: For damp, coastal or chemical exposure prefer A4/316 stainless or a suitable coating; indoors, plated steel or A2 is usually sufficient.
- Standard: This product is supplied to Trade series (roof insulation fasteners and plates). Quoting the standard on your order guarantees interchangeable dimensions between suppliers.
Where Heavy-Duty Roofing Insulation Fasteners Are Not the Right Choice
Match the fastener to the load, environment and whether the joint must be reopened; the wrong class or style is the usual cause of joint failure.
