Working with Pultrusions

By their very nature, Pultrusions can be applied in a huge range of applications, however care must be taken when working with them. Learn more about techniques and tips for when you’re working with pultrusions below.

Sawing

By Hand – A hacksaw with a steel blade or preferably a Tungsten or Diamond gritted blade for easier cutting
Circular Saw – Preferred option for volume cutting. Optimum cutting speed 3000metres/minute
Ceramic Blade with water jet to avoid burn marks (slurry collection required for the sawdust) OR Electroplated Nickel with Diamond. Use water jetting with slurry collection for longest blade life. Dry cutting requires dust extraction equipment

Routing

For best results, use an electroplated diamond blade

Shearing and Punching

Wider punch clearances preferred and, for large quantities, special punching pultrusion formulations can be formulated

Special tools required

Fastening

Self-tapping screws in pre-drilled holes or normal nuts and bolts. Crimped and/or bonded tube ends are also satisfactory

Drilling

Normal high-speed twist drills using the same feeds and speeds as for aluminium. Special drills can be obtained for modular drilling

Sanding

Standard woodworking machines are used. Dust extraction is recommended

Bonding

Surface must be abraded and degreased prior to bonding. Epoxy adhesives give good results

Painting

Stoved or unstoved paints can be used. Epoxy undercoats give the best adhesion, but polyester and polyurethane undercoats also give excellent results. Any compatible top coat can be applied
