Steel Grating Manufacturer — Tesco Factory, India
Galvanized Welded Steel Grating Panels
Because the surface is open, steel grating lets light, air, water, snow and debris pass straight through, keeping walkways drained, ventilated and slip-resistant. Yet a grating panel carries surprisingly high loads for its weight — the reason its tagline is “the perfect choice for heavy loads with minimal weight.” The bearing-bar size, depth and pitch set the load capacity, while the cross-bar pitch sets the size of the mesh opening. We manufacture every grating to suit the load, span, environment and finish your project needs.
The most popular and versatile type. Bearing bars are automatically resistance-welded to the cross bars under intense heat and pressure, making a rugged one-piece panel that is rigid yet smooth and safe to walk on — anti-slip, corrosion-resistant, free-draining and high in load capacity. Used for walkways, safety barriers, drainage covers, platforms, ventilation grates and stair treads.
Interlocking perpendicular bars are fused by enormous hydraulic pressure (no welding) — the deep cross bar is forced into a notched bearing bar for a permanent mechanical lock. Same strength and openness as welded grating, with a clean flush finish often preferred for architectural floors, ceilings, fences and removable covers.

| Material | Typical finish | Best for |
|---|---|---|
| Mild Steel / Carbon Steel | Hot-dip galvanized or painted | General industrial walkways, platforms, drain covers — the economical default |
| SS 304 | Untreated (self-finish) | Corrosion resistance, hygiene, food & general stainless service |
| SS 316 | Untreated | Marine, offshore, chloride & chemical environments |
| SS 310 | Untreated | High-temperature areas (furnaces, hot platforms) |
| SS 321 | Untreated | Elevated-temperature, stabilised stainless service |
| High-Nickel Alloys | Untreated | The most aggressive corrosive / high-temperature duty |
The most common finish for carbon-steel grating — a thick zinc coating for long-life corrosion protection outdoors and in wet areas.
Primer or finish paint where a specific colour or lighter-duty protection is wanted.
For stainless and nickel-alloy grating, which resist corrosion without a coating, and for carbon grating to be coated on site.
Steel grating is installed either by welding (permanent — welds at the bearing-bar ends and intermediate supports, typically 3/16″ × 3/4″ minimum for pedestrian use) or with grating fasteners where it must be removable or welding is impractical:
| Fastener | Use |
|---|---|
| Saddle clip | Bridges two bearing bars, fixed with a self-tapping bolt, self-threader, weld stud or bolt & nut |
| G-clip | Fastens grating to a horizontal-facing steel member edge |
| Grate-fast clip | Rapid, secure connection of open-grate flooring to steel sections |
| Use | Where |
|---|---|
| Walkways & platforms | Industrial walkways, access platforms, mezzanines, observation towers |
| Stair treads | Serrated grating stair treads with nosing for safe, slip-resistant stairs |
| Flooring | Plant flooring, raised floors, machine surrounds |
| Drainage | Drainage & trench covers, gully and channel grates |
| Bridge decks & ceilings | Bridge decking, ventilation grates, ceilings, sun-shade panels |
| Industries | Oil & gas, petrochemical, power, water treatment, infrastructure, commercial buildings |

What is steel grating?
Steel grating is an open-floor metal panel made of load-bearing bars (bearing bars) joined by transverse cross bars, forming a strong, rigid grid. It gives a high-strength, anti-slip walking and load surface that lets light, air, water and debris pass through, at a fraction of the weight of solid plate — which is why it is used for industrial walkways, platforms, stair treads, drainage covers and flooring.
What is welded steel grating?
Welded steel grating is the most common and versatile type. The bearing bars are automatically resistance-welded to the cross bars under intense heat and pressure, producing a rugged one-piece panel that is extremely rigid yet smooth and safe to walk on. It is anti-slip, corrosion-resistant, free-draining and has high strength and load capacity, used for walkways, platforms, drainage covers, stair treads and ventilation grates.
What is press-locked steel grating?
Press-locked steel grating uses interlocking perpendicular bars fused by enormous hydraulic pressure instead of welding — the deep cross bar is forced into a notched bearing bar for a permanent mechanical lock. It offers the same strength, durability and openness as welded grating with a clean, flush appearance, and is widely used for floors, platforms, ceilings, fences and covers.
What is the difference between welded and press-locked grating?
Both have bearing bars and cross bars and similar strength and openness. Welded grating is resistance-welded into a one-piece panel — rugged and economical, the default choice. Press-locked grating is fused by hydraulic pressure (no welding), giving a flush, decorative finish often preferred for architectural and removable applications. Both are made in carbon and stainless steel, plain or serrated.
What are bearing bars and cross bars?
The bearing bars are the main load-carrying bars that run in the span (load) direction and rest on the supports; the cross bars run perpendicular to them and hold the bearing bars together and keep them upright. The bearing-bar size, depth and pitch set the load capacity, while the cross-bar pitch sets the mesh opening.
What bearing bar types are available?
Flat bar (plain), serrated (with anti-slip teeth on top), I-bar (an I-section bearing bar that saves weight for a given depth) and serrated I-bar. Cross bars can be round or square-twisted. The surface can be plain or serrated for extra grip.
What is serrated steel grating and when is it used?
Serrated grating has saw-tooth notches along the top of the bearing bars (and on press-locked types, optionally the cross bars too) that bite into footwear for a high-grip, anti-slip surface. It is specified for wet, oily, icy or sloped walkways and stair treads where slip resistance is a safety requirement; plain (smooth) grating is used elsewhere.
What materials and grades is steel grating made from?
We make steel grating in mild steel and carbon steel (usually hot-dip galvanized), and in stainless steels SS 304, SS 316, SS 310 and SS 321, as well as high-nickel alloys for the most corrosive or high-temperature service. The grade is matched to the environment, and every grating is made to the customer's drawings and material specifications.
Can steel grating be made in stainless steel or nickel alloy?
Yes. We manufacture stainless steel grating in SS 304, SS 316, SS 310 and SS 321 for corrosive, hygienic or high-temperature environments — chemical, food, marine, offshore and furnace areas — and high-nickel-alloy grating for the most aggressive duty, all to customer specification.
What finishes are available for steel grating?
Hot-dip galvanized (the most common, for corrosion protection on carbon-steel grating), painted, or untreated / self-finish (typical for stainless grating, which needs no coating). The finish is chosen for the environment and the look required.
What sizes and bearing bar pitches do you offer?
We make standard welded grating with bearing-bar pitches of W-15 (15/16″), W-11 (11/16″) and heavy-duty W-19 (1-3/16″) and W-22 (1-3/8″), in bearing-bar sizes from about 3/4″ × 1/8″ up to 2-1/2″ × 3/16″ (and heavier for HD), with 2″ or 4″ cross-bar pitch. Full size and weight tables are in the catalog below, and custom sizes are made to drawing.
How do I specify or order steel grating?
Give us the material, grating type (welded or press-locked), bearing-bar size and pitch, cross-bar size and pitch, the span (bearing-bar direction) and panel size, the finish (galvanized / painted / untreated) and surface (plain / serrated), and the anchorage (welded, saddle clip, G-clip or grate-fast clip). If you are unsure, send your drawing or the load and span and we will recommend a grating.
How is steel grating installed?
Two ways: by welding (for permanent installation — welds at the ends of the bearing bars and at intermediate supports, typically 3/16″ × 3/4″ minimum for pedestrian use) or with grating fasteners (where the grating must be removable or welding is impractical). Common fasteners are saddle clips, G-clips and grate-fast clips, which secure the grating to the supporting steel without damaging a galvanized coating.
What are the common applications of steel grating?
Industrial walkways and platforms, mezzanines, stair treads, flooring, drainage and trench covers, ventilation grates, bridge decks, observation towers, ceilings and sun-shade panels — across oil & gas, petrochemical, power, water-treatment, infrastructure and commercial buildings, for both permanent and temporary use.
Do you make custom steel grating to drawing?
Yes. Most grating is made to order — we manufacture panels, stair treads, trench covers and shaped pieces to your drawings, dimensions and material specifications, with cut-outs, banding (edge binding), kick plates, nosings and toe-plates as required.
Do you provide test certificates and load test reports for steel grating?
Yes. Grating is inspected for appearance, sizing (bearing-bar and cross-bar size, panel dimensions) and load performance, and we provide mill test certificates for the material and a load / performance test report where required. Tesco Steel & Engineering is an ISO 9001:2015 certified manufacturer.
Why is steel grating preferred over solid steel plate flooring?
Steel grating carries heavy loads at a fraction of the weight of solid plate (its tagline is “heavy loads with minimal weight”), and its open surface lets light, air, water, snow and debris pass through — keeping walkways drained, ventilated and slip-resistant. That makes it safer and lighter than plate for industrial floors, platforms and walkways.
Where is your steel grating manufactured and do you export?
Our steel grating is manufactured at Tesco Steel & Engineering's works in Maharashtra, India (head office in Mumbai, with factory units near Bhayandar/Thane and Dahanu/Palghar), and exported worldwide in firm wooden or steel-pallet export packing. We are an ISO 9001:2015 certified manufacturer and exporter.
