Checkered Steel Plate

Tianjin Shunchen Industrial is a leading steel product manufacturer with 12 years of export experience, specializing in multi-functional structural steel materials. Our Tianjin production base is equipped with 3 fully automatic embossing rolling production lines and a national-level material testing laboratory, focusing on R&D and production of hot-rolled & cold-rolled anti-slip checkered plates applicable to heavy-load industrial, coastal humid, municipal public and vehicle manufacturing scenarios.

Different from smooth flat steel plates without anti-slip texture, our checkered steel plates form integrated raised patterns (diamond, lentil, one-bar, three-bar) through synchronous rolling molding, with firmly combined patterns that never peel or fall off. We adopt precise thickness and pattern height closed-loop control technology. Our QC supervisor with 10 years of metal plate testing experience supervises full-process inspection for every batch, ensuring pattern height deviation ≤0.1mm, stable thickness tolerance, crack-free and pit-free surface without delamination. All products comply with GB, ASTM, EN and JIS standards, and can provide complete mill test certificates (MTC EN 10204 3.1) and third-party SGS inspection reports.

Real-world Performance Testing

1. Anti-slip Friction Coefficient Test (Third-party SGS Test)

Test Standard: ASTM E303-22 Slip Resistance Test

Test Conditions: Dry & wet dual working conditions, 20kg test load, standard rubber friction head

Test Samples:

Ordinary flat carbon steel plate

3mm diamond Q235B checkered plate

6mm lentil Q355B checkered plate

Key Findings:

Ordinary flat plate wet friction coefficient: 0.23, extremely slippery with high fall risk

Q235B diamond plate wet friction coefficient: 0.58, anti-slip performance increased by 152%

Q355B lentil plate wet friction coefficient: 0.67, anti-slip performance increased by 191%

2. Load Bearing & Bending Mechanical Verification

Tested under standard room-temperature compression, core mechanical indicators as follows:

Q235B checkered plate: Tensile strength ≥375MPa, yield strength ≥235MPa

Q355B checkered plate: Tensile strength ≥470MPa, yield strength ≥355MPa

The embossed pattern forms a reinforced structure, greatly improving overall plate rigidity and effectively reducing bending deformation under uniform heavy load, suitable for long-span platform laying.

3. Neutral Salt Spray Corrosion Resistance Test

Test Standard: ASTM B117 Neutral Salt Spray Test

Test Conditions: Continuous spraying of 5% sodium chloride solution

Test Results:

Uncoated ordinary flat plate: Red rust appears after 120 hours

Original hot-rolled black checkered plate: No obvious rust after 320 hours

Custom hot-dip galvanized checkered plate: No rust or coating damage after 1800 hours

Real-world User Scenarios & Verified Cases

Case 1: Port Cargo Platform Renovation Project (Singapore Port Logistics Co., Ltd.)

Problem: Original flat steel platforms were extremely slippery on rainy days, causing frequent slip accidents; thin steel plates deformed severely under heavy container loads, requiring annual replacement and incurring high safety management costs.

Solution: Adopt 6mm Q355B lentil checkered plate, customized hot-dip galvanized anti-corrosion treatment to adapt to coastal salt fog environment.

Result: After 8 years of outdoor port service, no large-area deformation occurred, surface anti-slip performance remained stable, slip accident rate dropped by 90%, annual platform maintenance cost reduced by 72%. Annual purchase volume reaches 1100 tons, maintaining 6 consecutive years of stable cooperation.

Case 2: Factory Workshop Stair & Walkway Project (Zhejiang Heavy Equipment Manufacturing Co., Ltd.)

Industry: Industrial factory construction

Problem: Original cement stair treads wear rapidly, easily accumulate mechanical oil and become slippery; imported anti-slip plates have long delivery cycles and high procurement costs.

Solution: Adopt 3mm Q235B diamond checkered plate, custom fixed-size cutting for on-site welding installation.

Result: Oil stains are easy to clean, stable anti-slip effect under oily and humid workshop environment, service life extended from 2 years to 9 years, material cost reduced by 45% compared with imported alternatives. The factory fully adopted our checkered plates for all passages and stairs in Phase II expansion.

Case 3: Urban Bus Station & Pedestrian Overpass Municipal Project (Central China Municipal Construction Group)

Industry: Municipal public construction

Problem: Municipal pedestrian passages require both anti-slip function and unified landscape aesthetics; ordinary anti-slip plates have uneven patterns and poor flatness, failing municipal acceptance standards.

Solution: Cold-rolled fine one-bar checkered plate with uniform pattern height, customized color paint coating to match urban landscape design.

Result: Uniform surface texture, reliable anti-slip performance under heavy pedestrian flow and rainy weather, passed municipal one-time acceptance. Widely promoted for pedestrian overpasses, bus platforms and park walkways across multiple cities.
