Every pultruded profile NA-ME Composite makes is a constant cross-section drawn from a heated die. That single fact is what lets a structural shape behave the same way on its first meter and its last. This page brings the whole family together: what each section is good at, the standard sizes we hold, and where each one usually ends up on site.
Six shapes cover the large majority of industrial work. Where they do not, we cut a die for the section your project needs.
| Family | Standard range | Sections | Typically used for |
|---|---|---|---|
| GRP Channel (U) | 30×20×3 to 300×75×12 mm | 18 | Platform edges, cable routes, frames and general framing |
| GRP C-Channel | 56×24×2 to 200×55×9 mm | from the channel range | Hangers, rails and cable tray supports bolted from the side |
| GRP Angle | 20×20×4 to 255×32×3 mm | 12 | Grating edges, frames and corner joints |
| GRP I-Beam | 30×15×4 to 300×150×12 mm | 9 | Spanning between supports where deflection is limited |
| GRP Square Tube & Box | 25×25×3 to 350×60×6 mm | 52 | Posts, frame corners, cantilevers and torsion-loaded members |
| GRP Round Tube | Ø20×3 to Ø58×2 mm | 23 | Handrail posts and top rails, cable protection, light members |
| GRP Flat Bar | 20×5 to 100×12 mm, plus 500–850 mm wide | 19 | Connection plates, edge trim, grating fixings, walking surfaces |
| GRP Rod | Ø4 to Ø55 mm | 19 | Pins, dowels, insulating spacers, tie bars |
| GRP Special Sections | handrail, toe board, knurled tube | 12 | Purpose-made shapes, and a die cut for a section not listed here |
Three questions settle it almost every time. What load will it carry and over what span? How aggressive is the environment: chemicals, salt, moisture, UV? And does the job need electrical insulation? The answers point at a section, a resin system and a surface veil together, because on site those three arrive as one decision.
If deflection rather than strength is what worries you, start at mechanical properties and load capacity. If the material itself is new to you, what is an FRP profile and GRP vs FRP cover the ground in a few minutes.
A pultruded structural shape does not rust, weighs roughly a quarter of steel, and conducts neither electricity nor heat. In treatment plants, chemical sites, marine structures and solar plants, those three properties remove the maintenance cycle that steel brings with it. See applications by industry for where each shape earns its place, or handrail and platform systems for complete assemblies built from these sections together with NA-ME FRP grating.
If the standard family does not fit, send a sketch or the dimensions of a sample. We will tell you at a glance whether a new die is needed, and what that means for lead time and quantity. Everything about how the shapes are made is on the pultrusion process page, and how we keep them repeatable is on quality, standards and testing.
