Electroforged Gratings Stronger Panels, Near-Zero Joint Defects
The electro-forging process fuses each cross bar into the bearing bar without filler metal, so there are no cracks or open joints where corrosion can start. The full strength of the bearing bar is retained, while the square twisted cross bar gives the surface reliable anti-skid grip for oily or wet platforms.
- Consistent panel geometry from automated PLC control
- Fast lead times for repeat sizes and large platform packages
- Supplied black, painted or hot-dip galvanized
Corrosion Resistance
Stainless Steel Gratings Pressure Welded, Acid Washed & Electro-Polished
Stainless gratings are assembled and welded to specification using raw material conforming to AISI 304, AISI 316 or AISI 309, or to the grade stated in your purchase order. After welding, panels are acid washed and electro-polished to remove heat tint and restore the passive layer for a clean, long-life finish.
- Food, dairy, pharmaceutical and clean-room floors
- Coastal, marine and chloride-exposed structures (AISI 316)
- Elevated-temperature process zones (AISI 309)
Fabrication Flexibility
Welded / Custom Made Gratings Any Shape, Any Cut-Out
Round, square and irregular cut-outs for pipes, columns and equipment can be built into pressed and electroforged panels, either inside the panel or along the outside edge. Every cut-out is banded with flat bar for load transfer and safe edges, and toe plates can be added for platform perimeters.
- Panels marked and packed to match your layout drawing
- Trench covers, platforms and complex structures
- Mild steel, stainless steel and aluminium

Buyer's Selection Guide
Which Grating Fits Your Application?
A quick engineering comparison used by our team when reviewing tenders. Final selection should always be confirmed against span, load and site environment.
| Grating Type | Best Suited For | Typical Material | Finish Options | Key Advantage |
|---|---|---|---|---|
| Electroforged | Platforms, walkways, mezzanines, trench covers | Mild steel, stainless steel | Black, painted, hot-dip galvanized | Seamless fused joints, high volume consistency |
| Stainless Steel | Food, pharma, marine, chemical plants | AISI 304 / 316 / 309 | Acid washed, electro-polished | Corrosion resistance, hygienic surface |
| Heavy Duty Welded | Loading docks, highways, airfields, ramps | Mild steel, deep bearing bars | Hot-dip galvanized | Rated for vehicle and wheel loads |
| FRP / Fiberglass | Chemical, water treatment, offshore, electrical rooms | Glass-reinforced resin | Concave or grit-top surface | Lightweight, non-conductive, rust-free |
| Expanded Metal | Catwalks, machine guards, screens, fencing | Mild steel, stainless, aluminium | Galvanized, painted | Up to 80% lighter, no welded joints |
| Non-Ferrous | Weight-sensitive and spark-sensitive areas | Aluminium | Mill finish | Low weight, naturally corrosion resistant |

FAQ
Grating Questions from Procurement Teams
What is the difference between electroforged and manually welded gratings?
Electroforged gratings are produced on PLC-controlled machines that apply more than 100 tonnes of hydraulic pressure and approximately 2200 A of current to fuse every cross bar into the bearing bar, creating a seamless joint with no open welds. Manually welded gratings are fabricated panel by panel and are preferred for non-standard shapes, heavy bar sections and complex cut-outs.
Which stainless steel grade should I choose for coastal or chemical environments?
AISI 304 suits most food, pharmaceutical and indoor process areas. AISI 316 contains molybdenum and is recommended for marine, coastal and chloride-rich chemical environments. AISI 309 is used where higher temperature resistance is needed. Gratings are acid washed and electro-polished after welding.
Can gratings be fabricated with cut-outs, toe plates and banding?
Yes. Round, square and edge cut-outs can be incorporated in pressure-welded and electroforged panels, and every cut-out is banded with flat bar. Custom panels are typically produced in widths from 250 mm up to 1200 mm with lengths as required by the project drawing.
What information is needed to evaluate a grating requirement?
Share the bearing bar size, bar pitch, cross bar pitch, panel dimensions, material grade, surface finish, design load or span, quantity, required standards and destination port. Layout drawings speed up engineering review.
Is FRP grating a suitable replacement for steel grating?
FRP and fiberglass gratings weigh much less than steel, do not corrode and are non-conductive, which makes them suitable for chemical plants, water treatment, offshore and electrical areas. Load capacity depends on panel depth and span, so the section should be selected against the design load.
