Project Background
An Indian construction contractor sourcing materials for a multi-building site in South India needed a walkway and platform surface that would stay safe in monsoon conditions. The site operates with daily foot traffic from 200+ workers, plus wheelbarrow and light equipment movement across temporary access routes, so the flooring had to combine slip resistance, structural rigidity and a light own weight.
After comparing local stock against imported options, the buyer selected our five-bar checkered aluminum plate in 1060 H24, 4mm thickness, cut to 1200 x 2400mm, with a total order quantity of 10 tons.
Why 5-Bar Checkered Aluminum Plate
The five-bar pattern (also written 5 bar, five bar or 5-bar tread plate) is the standard anti-slip geometry for construction site flooring. Each bar is raised and angled in two directions, so grip works whether the worker walks along or across the sheet, and water drains away instead of pooling on the surface.
- Directional grip - the five raised bars form a herringbone layout that resists slipping in both directions, unlike a single-direction rib pattern
- Self-draining surface - open channels between the bars let monsoon rain run off quickly, reducing standing water and mud build-up
- Wear resistant walking face - the raised bars take the abrasion from boots and wheelbarrow wheels, protecting the flat base metal underneath
- Visible safety surface - mill finish reflects daylight, so the walkway edge stays visible on a busy site
Material Selection: 1060 H24
| Parameter | Specification | Why It Matters On Site |
|---|---|---|
| Alloy | 1060 (99.6% pure aluminum) | Excellent corrosion resistance in humid, coastal air; no rust staining on concrete or scaffolding |
| Temper | H24 (strain hardened and stabilised) | Half-hard condition gives enough rigidity for a 4mm span while still allowing on-site cutting and drilling |
| Thickness | 4mm | Carries foot traffic and light trolley loads without visible deflection on supported spans |
| Sheet Size | 1200 x 2400mm | Matches standard site plank spacing and container loading, minimal offcut waste |
| Pattern | 5 bar / five bar checkered | Anti-slip geometry for wet and dusty conditions |
| Surface | Mill finish | No coating to chip or peel; ready for immediate use after delivery |
| Quantity | 10 tons (approx. 320 sheets) | Covers the site's walkway, stair tread and platform requirement in one shipment |
Order and Logistics
The order was confirmed at 10 tons, packed on seaworthy wooden pallets of roughly 1.5 to 2 tons each with interleaved protection and edge boards, then shipped by sea from Qingdao to an Indian west coast port. Production and inspection were completed in 10 working days, with mill test certificate, packing list and commercial invoice issued together with the shipment.
- Sheets per ton: approximately 32 sheets of 4mm 1200 x 2400mm (each sheet weighs about 31.2kg)
- Total sheets: approximately 320 sheets for the 10 ton lot
- Packing: wooden pallet, 1.5 to 2 tons per pallet, waterproof paper and VCI film for the sea leg
- Lead time: 10 working days for production, plus ocean transit
- Documents: mill test certificate, packing list, commercial invoice, certificate of origin
On-Site Results
- Slip incidents reduced - the five-bar surface stayed grippy through the monsoon season without the sanding and re-coating that timber planks would have needed
- Reusable across phases - sheets were lifted, moved and re-laid on the next building block instead of being scrapped, because aluminum does not rot, swell or delaminate
- Lower handling cost - at about 31kg per sheet, two workers can position a 1200 x 2400mm panel without a crane, cutting installation time
- No corrosion staining - mill finish 1060 stayed clean in high humidity, protecting the appearance of finished concrete surfaces below
- Predictable repeat supply - the buyer now orders the same 4mm 1060 H24 1200 x 2400mm specification in fixed lots, so site planning and pricing stay stable
Why This Specification Works For Indian Construction Sites
India's construction season is bracketed by heat and heavy rain. A 4mm 1060 H24 five-bar plate handles both: the alloy resists the humid, dust-laden air without rusting, while the raised bar pattern keeps grip on wet surfaces. The 1200 x 2400mm format is also practical — it is light enough to move by hand, large enough to cover a walkway quickly, and efficient to load in a 20GP container with minimal waste.
