1. Product Definition & Core Overview
Patterned steel plate, also known as anti-slip steel plate or tread plate, is a special hot-rolled steel plate formed by professional patterned rolls. The plate surface features regular raised patterns, including lenticular, diamond, round bean and mixed oval-round patterns. Featuring excellent anti-slip performance, high wear resistance, strong compression and bending resistance, attractive appearance and good rust resistance, the product boasts high overall structural strength and non-deformation performance. It is a special steel material widely used for industrial platforms, stair treads, anti-slip flooring and walkway paving.
Manufactured with carbon structural steel substrate through integrated hot rolling, the patterned layer is tightly bonded to the base plate without peeling or delamination. The plate can be directly cut, bent, welded and punched without secondary surface treatment, and is extensively applied in factory buildings, shipyards, vehicles, municipal engineering and mechanical anti-slip structures.
2. Executive Standards
GB/T 3277-2015 Hot-rolled patterned steel plates (core national standard)
GB/T 700 Carbon structural steels
GB/T 709 Dimension, shape, mass and tolerance of hot-rolled steel plates and strips
ISO 7802 International general standard for anti-slip patterned steel plates
JIS G3101 Japanese standard for structural patterned steel plates
3. Product Classification & Pattern Types
3.1 Classification by Pattern Style
Lenticular Pattern (Most Common): Outstanding anti-slip performance, high wear resistance, strong load-bearing capacity and low dust accumulation. It is the mainstream choice for industrial plants, shipyards and factories.
Diamond Pattern: Regular three-dimensional pattern with excellent decorative effect, suitable for equipment casings and aesthetic walkways.
Round Bean Pattern: Uniform friction and comfortable walking experience, mostly used for vehicle chassis and carriage bottom plates.
Mixed Pattern: Combined oval and round structure with balanced anti-slip and load-bearing performance, ideal for high-end equipment platforms.
3.2 Classification by Material
Ordinary Carbon Patterned Steel (Q235B): Good toughness, excellent weldability and cost performance, serving as the mainstream material for general applications.
Low-Alloy Patterned Steel (Q355B): Higher strength, superior impact resistance and load-bearing capacity, specially used for heavy-duty equipment and large-scale platforms.
3.3 Classification by Production Process
Integrated Hot-Rolled Patterned Plate: The substrate and pattern are rolled synchronously with firm bonding, no cracking or pattern falling off, complying with national standard quality requirements.
Secondary Embossed Plate: Formed by re-embossing ordinary flat plates with shallow patterns and poor adhesion, only applicable for simple decorative purposes.
4. Specification Range
The thickness of patterned steel plate refers to base plate thickness (excluding pattern height), strictly implemented in accordance with national standard measurement rules.
Common Thickness: 2.0mm, 2.5mm, 3.0mm, 3.5mm, 4.0mm, 5.0mm, 6.0mm, 8.0mm, 10mm
Standard Width: 1000mm, 1250mm, 1500mm, 1800mm, 2000mm
Standard Length: 6000mm, 8000mm, 10000mm, 12000mm
Pattern Height: 0.3～1.5mm (matched with different thickness specifications per national standard)
Delivery Forms: Original flat plates, custom fixed-size cutting, special-shaped cutting, bending processing and beveling processing
5. Mechanical Properties & Quality Standards
Yield Strength: ≥235MPa (Q235B), ≥355MPa (Q355B)
Tensile Strength: 370–500MPa
Elongation after Fracture: ≥26%, with excellent ductility for bending, punching and welding
Processing Performance: No cracks after 180° cold bending; no pattern peeling or flaking
Surface Quality: Flat and neat plate surface with clear, full and evenly distributed patterns; free of cracks, scars, folds, bubbles and delamination defects
6. Production Process Flow
Steel billet heating → High-pressure water descaling → Rough rolling shaping → Finish rolling & pattern embossing via special patterned rolls → Laminar flow cooling → Straightening & leveling → Fixed-length shearing → Surface quality inspection → Dimensional re-inspection → Marking & spraying → Packaging & warehousing
Adopting one-time integrated hot rolling molding, the patterns and substrate form a continuous integrated metallographic structure with ultra-strong adhesion. No pattern peeling or surface flaking occurs under long-term load bearing, treading and friction.
7. Core Product Advantages
Excellent Anti-Slip Performance: Three-dimensional raised patterns greatly increase friction coefficient, effectively preventing slipping and falling in humid, oily and outdoor working environments.
High Structural Strength & Load Capacity: The patterned structure acts as reinforcing ribs, providing better bending and compression resistance than ordinary flat plates with stable non-deformation performance.
Firm & Durable Patterns: Integrated hot rolling process eliminates delamination and pattern falling, delivering a far longer service life than secondary embossed plates.
Superior Processing Adaptability: Supports arbitrary cutting, bending, welding, punching and grinding with convenient construction operation.
Good Corrosion Resistance & Durability: Carbon steel substrate features stable physical and chemical properties; painting or hot-dip galvanizing treatment can significantly extend outdoor service life.
Neat Appearance & Wide Applicability: Uniform plate surface and regular patterns achieve perfect integration of functional performance and decorative effect.
8. Main Application Fields
Industrial Plants: Workshop platforms, walkway treads, equipment anti-slip flooring, trench cover plates
Construction Engineering: Steel structure stair treads, roof maintenance walkways, trestle tread plates
Ship & Port Industry: Cabin treads, deck anti-slip plates, port walkways, port equipment platforms
Vehicle & Transportation Industry: Truck carriage bottom plates, engineering vehicle anti-slip floors, car washing platforms
Municipal Facilities: Overpass treads, civil air defense projects, underground passage anti-slip flooring
Mechanical Equipment: Large equipment bases, frame tread plates, operating platform anti-slip structures
9. Processing & Operation Specifications
Install with the patterned surface facing upward; reverse installation is prohibited to avoid loss of anti-slip effect.
Cutting and welding operations are consistent with ordinary steel plates without special processes required.
Painting or hot-dip galvanizing anti-corrosion treatment is recommended for long-term outdoor use to extend service life.
Plates with thickness above 3.0mm and Q355B high-strength material are preferred for heavy-duty platforms.
During bending processing, the inner substrate shall bear pressure and the outer patterned surface shall bear tension to prevent pattern cracking.
10. Packaging, Quality Assurance & Customization Services
Standard Packaging: Plates are stacked with wooden cushion blocks and integrally bundled with steel strips, with surface anti-scratch film coating, suitable for long-distance transportation.
Quality Documents: Material certificates, mechanical property test reports, factory qualification certificates and spectral inspection reports are available to support third-party acceptance.
Customization Services: Support non-standard fixed-size cutting, special-shaped processing, bending & punching, galvanizing anti-corrosion and sandblasting rust removal treatment.
