Checkered Plate Detailed Product Description
1. Product Definition
Checkered plate (also named anti-slip steel plate) is a metal plate with regular and continuous raised patterns pressed or hot-rolled on the surface of carbon steel substrate. It features anti-slip, load-bearing and decorative functions, widely used in industrial and construction fields.
2. Material & Executive Standards
Materials
Carbon Steel: Q235B (most common & cost-effective), Q355B (high strength)
Aluminum Alloy: 1060, 3003, 5052 (light weight & rust-proof for vehicle and decoration)
Executive Standards
National Standard: GB/T 3275-2015 Hot Rolled Checkered Steel Plate
Aluminum Alloy: GB/T 3618-2006
3. Common Pattern Types
Diamond Pattern: Best anti-slip performance, uniform stress, not easy to accumulate dirt; applied for industrial platforms, stair treads and ship decks.
Lentil Pattern: Smooth raised surface, comfortable walking experience, mainstream type in the market; used for building walkways, vehicle foot pedals and indoor floors.
Round Bean Pattern: Small raised grains, mild anti-slip effect and easy to clean; suitable for mall passages, toilet floors and light-duty equipment platforms.
Willow Leaf Pattern: Smooth lines with strong decoration, average anti-slip performance; applied for exterior wall decoration and landscape components.
4. Specification Parameters (Carbon Steel)
Base Thickness: 2.0–12mm (pattern height 0.5–2mm, not included in base thickness)
Width: 1000mm, 1220mm, 1500mm, 1800mm (customizable)
Length: 2000mm, 2440mm, 6000mm (custom cutting available)
5. Core Features
Anti-slip & Safety: Raised patterns greatly increase friction coefficient; dry anti-slip coefficient ≥0.6, wet ≥0.4, effectively prevent slipping and equipment displacement.
High Strength & Rigidity: Stable mechanical properties; Q355B can bear 2–5MPa pressure for heavy-load platforms; pattern structure enhances plate rigidity and avoids deformation.
Durable & Anti-corrosion: Carbon steel can be hot-dip galvanized for long service life; stainless steel resists acid and alkali, suitable for harsh environments.
Drainage & Easy Cleaning: Pattern gaps form natural drainage channels, reduce water and dust accumulation, easy for daily maintenance.
Economical & Decorative: Save steel consumption under equal strength; various pattern styles meet decorative demands.
6. Surface Treatment
Hot Rolled Original: Cost-effective for ordinary industrial occasions.
Hot-dip Galvanized / Galvalume: Excellent rust and corrosion resistance, service life extended 3–5 times, suitable for outdoor, humid and acid-base environments.
Stainless Steel Original / Brushed: Beautiful and corrosion-resistant, for food, pharmaceutical and chemical industries with high cleanliness requirements.
Spray Paint / Epoxy Anti-slip Paint: Improve anti-corrosion and anti-slip performance with optional colors.
7. Main Applications
Construction: Stair treads, platforms, walkways, warehouse floors, ditch cover plates.
Transportation: Truck/container bottom plates, pedestrian overpass anti-slip passages, ship decks and cabin floors.
Industry: Factory flooring, machine operation platforms, equipment base plates, pipeline support base plates.
Municipal & Agriculture: Pedestrian overpasses, drainage cover plates, farm flooring.
Decoration: Exterior walls, door panels, cabinet panels, landscape modeling.
8. Selection Guide
Ordinary environment & economy: Q235B + Lentil Pattern, thickness 3–5mm
Humid / Outdoor / Corrosive environment: Hot-dip Galvanized Q235B or 304 Stainless Steel
Heavy load & High strength: Q355B + Diamond Pattern, thickness 6–10mm
Decoration priority: Willow Leaf / Round Bean Pattern, thickness 2.5–4mm
9. Processing & Delivery
Processing Service: Custom cutting, bending, punching, welding, galvanizing as per drawings.
Delivery Cycle: 5–7 days for standard specifications; 7–15 days for customized products.
Shipping Port: Tianjin Port, Qingdao Port (FOB / CIF terms acceptable).
