5mm Checkered Plate

Checkered plates are aesthetically pleasing, slip-resistant, have enhanced strength, and offer steel savings, among other advantages. They are widely used in transportation, construction, decoration, equipment base plates, machinery, shipbuilding, and other fields. Generally, users do not impose high requirements on the mechanical or physical properties of checkered plates; thus, plate quality is primarily reflected in the pattern formation rate, pattern height, and height variation between patterns. Common market thicknesses range from 0.8 - 8 mm, with typical widths of 1250 mm and 1500 mm.

Specification Parameter

Product Quality Classification Standard

According to surface quality and pattern precision, our 5mm checkered plates are divided into Ordinary Precision and High Precision grades, meeting different engineering and commercial procurement standards:

1. Ordinary Precision Grade

The steel surface allows thin oxide scale, slight rust, and local rough surface caused by oxide scale falling off. Other local defects shall not exceed the allowable deviation of plate height and depth. Indistinct burrs and individual traces that do not exceed the pattern height are permitted on the patterns. The maximum area of single defect shall not exceed the square of the pattern length, ensuring basic anti-slip and structural use requirements for general engineering.

2. High Precision Grade

The steel surface allows only thin oxide scale and slight rust. The height and depth of all local defects shall not exceed half of the plate thickness tolerance. The patterns are complete and intact, with only tiny local burrs within half of the thickness tolerance. This grade features smoother surface, more uniform pattern height and higher flatness, suitable for high-standard construction decoration, precision equipment bases and high-end marine projects.

Production Technology

Complete Production Flow: Slab cold charging → Heating → High-pressure water descaling → Rough rolling → Hot coil box → Secondary high-pressure descaling → Finishing rolling → Laminar cooling → Coiling → Bundling → Warehouse storage.

Precise Temperature Control

Strictly implement fixed temperature system, with finishing rolling outlet temperature controlled at 870°C (±20°C) and coiling inlet temperature at 620°C (±20°C), ensuring uniform plate texture and stable mechanical properties.

Professional Roller Configuration

Adopt positive crown patterned roller for upper work roll and negative crown roller for lower work roll in the final finishing stand, matching micro-wave rolling strategy to ensure flat plate shape and consistent pattern height.

Process Optimization Upgrade

Optimized rolling technology enables high pattern height production, with maximum pattern height up to 1.2mm, meeting high anti-slip standard engineering needs.

FAQ

Q1: What are the surface treatments for 5mm checkered plate?

A1: We support multiple mainstream grades including Q235, Q345, SS400, S355 and ASTM A36. Optional surface treatments: black original surface, anti-rust oiled, painted and hot-dip galvanized. Customized treatment is acceptable per project demands.

Q2: What is the MOQ for bulk orders?

A2: Flexible MOQ supports trial small orders and large-scale engineering bulk procurement.

Q3: What is the warranty condition of the checkered plate?

A3: We provide 3–5 years quality warranty for all 5mm checkered plates. Under normal installation, dry or conventional outdoor working environment, no quality problems such as pattern falling, surface cracking and severe rusting will occur within the warranty period.

Q4: Can you provide custom cutting, bending and size processing?

A4: Yes. Sanhe Steel supports customization for special sizes and shaped plates are available to match different installation scenarios.

Q5: What is the difference between ordinary precision and high precision checkered plate?

A5: High precision plate has stricter surface defect control, smaller thickness tolerance deviation and more uniform pattern height, suitable for high-standard decoration, marine and export projects. Ordinary precision plate is cost-effective and more suitable for general industrial and construction engineering.
