Pre-galvanized steel
Zinc coating 40 / 80 / 275 g/m²
Indoor and dry environments; the economical standard for building services and light industrial runs.
Materials & finishes
The right finish for your environment
Most tray failures are finish failures, not steel failures. Below are the finishes from our catalog with the coating weights we actually produce — tell us where the tray will run and we will confirm the choice in writing on your quotation.
Hot-dip galvanized (HDG)
Zinc layer 45 / 65 / 85 µm
Outdoor, coastal and humid sites. The tray is galvanized after fabrication, so cut edges and welds are coated too.
Electro-galvanized (EG)
Zinc layer typically 8–25 µm
Clean indoor duties where a smooth, bright surface matters more than heavy corrosion duty.
Powder coated
Colour customisable
Colour-matched installations and an extra barrier layer over galvanized steel for architectural or branded projects.
Stainless steel 201 / 304 / 316
Grades 201, 304, 316
Food, chemical, wastewater and marine environments. 316 for the most aggressive chloride exposure.
Aluminum alloy
6061-T6 / 6063-T5
Lightweight runs and corrosion-resistant duties; board and extruded profiles available per catalog.
Base materials
| Carbon steel | Q235 — the standard tray material for galvanized and powder-coated systems |
|---|---|
| Stainless steel | Grades 201 / 304 / 316 for corrosive, hygienic and marine duties |
| Aluminum alloy | 6061-T6 / 6063-T5 — board and extruded profiles per catalog |
| ZAM | Zinc-aluminium-magnesium coated steel, listed in our catalog finishes |
How to choose — quick guide
- Dry indoor (offices, malls, plant rooms): pre-galvanized or electro-galvanized
- Outdoor / coastal / humid: hot-dip galvanized 65–85 µm
- Chemical, food, wastewater: stainless 304; chloride-heavy → 316
- Weight-sensitive or architectural: aluminum alloy, or powder coated over galvanized
Not sure? Send the project location and environment with your BOQ — the finish recommendation and its catalog basis will be written into the quotation, not left to a verbal promise.
