Forged from high-tensile bearing bars with square twisted cross rods. Provides 80% open area for instant drainage of snow, water, mud, and oil on exterior stair towers.
Export-Grade Industrial Stairway Solutions
Engineered Safety Treads & Guardrail Systems for Plants Worldwide
Omkar Gratings Pvt Ltd (Omkareshwar Engineering) fabricates heavy-duty stair treads and industrial safety handrailing systems designed for oil refineries, chemical plants, offshore platforms, power stations, and infrastructure projects.
Every tread unit features factory-welded anti-slip nosing and pre-punched carrier end-plates to allow immediate bolted or welded stringer installation. Available in electroforged bar grating, diamond pattern chequered plates, or corrosion-resistant stainless steel, each system satisfies stringent international safety requirements including OSHA 1910.28, BS 4592, and ISO 14122-3.

Product Configurations
Industrial Stair Tread Fabrication Types
Manufactured using electroforged or pressure-locked grating and high-tensile chequered plates with high-grip front nosing configurations.
Chequered Plate Treads
Solid-surface non-skid plate steps for applications requiring complete containment of fallen tools and liquids. Supplied with slotted side connection clips.
Stainless & Sanitary Treads
Engineered for food processing, cleanrooms, and coastal installations where exposure to acids, chlorides, or washdown detergents demands zero corrosion.

Heavy-Duty Heavy-Traffic Platform Steps Engineered Safety Features
Anti-Slip Nosing & Stringer Fixings Eliminating Slip and Fall Risks
The leading front edge of every stair tread receives approximately 85% of foot impact during descent. Omkar stair treads incorporate heavy-gauge safety nosing welded directly to the bearing bars, serving both as high-contrast visual cues and rugged slip protection.
- Checkered diamond plate nosing with deep traction ribs
- Perforated dimple nosing for wet, freezing, and marine wash zones
- Standard 65mm x 5mm end carrier plates pre-slotted for M12 bolts
- Deflection engineered below 1/200th of span under design live loads
Structural Guarding & Fall Protection
Industrial Handrailing & Stanchions Tubular, Angle & Kick Plate Systems
Omkareshwar Engineering manufactures industrial safety handrails, balustrades, and pedestrian guard systems for chemical tanks, walkway bridges, drilling skids, and elevated mezzanines. Systems are manufactured from ERW or seamless pipes, solid steel flats, and formed structural angles.
- Ball-type stanchions with forged or welded internal through-joints
- Integrated 100mm to 150mm kick plates (toe boards) to stop falling objects
- Base mounted, side-mounted (fascia), and core-drilled post connections
- Meets OSHA point-load criteria (minimum 200 lbs / 890 N top rail loading)

Frequently Asked Questions
Technical Inquiries for Plant Engineers
What standards do Omkar stair treads and handrails comply with?
Our products are engineered and tested in conformity with BS 4592 Parts 0 to 5, ISO 14122-3 (Safety of machinery - Permanent means of access), OSHA 1910.28 / 1910.29, and AS 1657. Specific design calculations and weld test reports can be furnished upon request.
What is the difference between welded and bolted stair tread connections?
Bolted stair treads feature factory-welded end-plates with slotted holes to accommodate slight structural tolerances and enable quick replacement without hot-work permits. Welded stair treads are fabricated without carrier plates and are tack-welded directly to the channel stringers during structural erection.
How do you ensure slip resistance on oily or wet platforms?
We combine serrated bearing bars with deep anti-skid checkered plate nosing or cast-in abrasive grit edges. The open grid design prevents accumulation of standing water, oil, drilling fluids, and snow, guaranteeing a high coefficient of friction.
Can Omkar supply matched handrail posts with toe plates (kick plates)?
Yes. We manufacture complete modular handrailing packages consisting of top rails, intermediate knee rails, and continuous steel toe plates (minimum 100mm height) with pre-welded attachment brackets to eliminate fall hazard vulnerabilities.
