Flat Grating

Flat grating is a kind of steel product that is made of flat steel and cross bars (twisted square steel, square steel, round steel, flat steel, etc.) arranged crosswise at a certain interval and welded into a square grid in the middle. Flat grating is mainly used for ditch covers, steel structure platform plates, steel ladder treads, etc. The cross bars are generally made of twisted square steel. Flat grating is generally made of carbon steel, and the surface is hot-dip galvanized to prevent oxidation. It can also be made of stainless steel. Flat grating has ventilation, lighting, heat dissipation, anti-slip, explosion-proof and other properties.

Classification

Flat grating is generally divided into galvanized flat grating, stainless steel flat grating, platform flat grating, ditch cover, composite flat grating, plug-in flat grating, toothed flat grating, special-shaped flat grating, etc.

Application Scenario

1. Industrial field

Platforms and walkways: used for operating platforms and maintenance passages in factory workshops, mines, docks, etc., with strong bearing capacity and good ventilation and heat dissipation.
Equipment support: used as the base or shelf layer of heavy machinery, such as warehouse shelves and ball mill perimeter protection.
Anti-slip facilities: Toothed flat grating is often used in humid environments such as oil fields and ship decks to prevent people from slipping.

2. Municipal and public facilities

Drainage system: used as ditch covers and inspection well covers, which can quickly drain water and prevent blockage, reducing the risk of urban waterlogging.
Guardrails and enclosures: Guardrails on both sides of industrial parks and bridges, with both safety and transparency.
Architecture and decoration
Stair treads: Anti-slip design ensures safety, commonly seen in public places such as shopping malls and subway stations.
Indoor and outdoor decoration: used for suspended ceilings, curtain walls or balcony fences to create an industrial style aesthetic effect.

3. Transportation and Environmental Engineering

Bridges and Tunnels: Inspection channels, drainage grilles and guardrails are corrosion-resistant and have low maintenance costs.
Sewage Treatment: Sewage pool platforms and sludge treatment areas are resistant to corrosive substances.

4. Special Scenarios

Marine Engineering: Offshore oil platforms use stainless steel or hot-dip galvanized flat grating (hot-dip galvanizing treatment) to adapt to high salt spray environments.
Logistics Warehousing: Shelf layers optimize space utilization and are light-permeable and ventilated.

Selection and adaptation suggestions

Process type

Pressed welding type for heavy-duty scenarios, I-shaped flat grating for lightweight requirements.

Material selection

Carbon steel (economical and durable) for ordinary environments, stainless steel or aluminum alloy for highly corrosive environments.

Surface treatment

Hot-dip galvanizing is recommended for outdoor or humid environments to extend service life.
