I. Product Overview
Checkered plate (also known as anti-slip plate or embossed plate) refers to a metal plate with regular raised patterns rolled or stamped on its surface. Its core functions are anti-slip, load-bearing, wear-resistant, and basic decorative properties. It features stable mechanical properties and high cost performance, and is widely used in industrial manufacturing, construction, transportation, municipal facilities and other fields. English Name: Diamond Plate/Checkered Plate. It complies with the national standard GB/T 33974-2017 "Hot-rolled Checkered Steel Plates and Strips", and all indicators meet the requirements of current national specifications.
II. Material Classification and Core Characteristics
Material Type |
Common Grades |
Core Performance |
Application Scenarios |
Carbon Structural Steel (Mainstream) |
Q235B, Q355B |
High yield strength, good impact resistance, excellent welding performance and convenient processing; bare plates are prone to oxidation and rust, and can be treated with galvanizing or painting for anti-corrosion to improve durability. |
Industrial operating platforms, stair treads, truck compartment floors, scaffolding planks, trench covers, heavy equipment bases. |
Aluminum Alloy |
5052, 6061 |
Light weight, corrosion resistance, not easy to rust, strong plasticity and smooth surface; overall strength is lower than carbon steel, suitable for light-load scenarios. |
Passenger car interior floors, light equipment tables, indoor decorative components, aviation light-load parts, wet light-load walkways. |
III. Pattern Types and Specification Parameters
(1) Mainstream National Standard Pattern Styles
Lentil Shape (Industry First Choice): The pattern is in the shape of long arc protrusions, with the best anti-slip performance and smooth drainage. It is suitable for harsh working conditions such as humidity, oil pollution and heavy dust, and has the highest application coverage.
Diamond Shape: Continuous diamond convex structure, uniform force bearing, strong load-bearing stability and good plate flatness, suitable for heavy-duty industrial platforms and fixed walkways.
Round Bean Shape: Round dot protrusions, gentle surface touch, moderate friction, balancing anti-slip performance and walking comfort, suitable for light anti-slip and indoor walkways.
Combined Shape: Mixed arrangement of lentil and round patterns, balancing anti-slip and decorative properties, suitable for industrial and architectural scenarios with certain appearance requirements.
(2) Core Specification Parameters
Base Plate Thickness: 1.4–16mm, mainstream common specifications are 2.0–8mm. The height of the pattern protrusion is ≥20% of the base plate thickness to ensure anti-slip effect.
Standard Width: 1000mm, 1250mm, 1500mm (custom cutting available).
Standard Length: 2000mm, 6000mm (custom length cutting and slitting available on demand).
Theoretical Weight Reference (kg/㎡, base plate + pattern weight gain):
2.5mm: Diamond 21.6, Lentil 21.3, Round Bean 21.1
3.0mm: Diamond 25.6, Lentil 24.4, Round Bean 24.3
4.0mm: Diamond 34.4, Lentil 33.4, Round Bean 33.2
IV. Production Process
Hot Rolling Process (Mainstream): Steel billet heating → rough rolling forming → finish rolling shaping → special pattern roll rolling → temperature-controlled cooling → straightening → fixed-length cutting. The pattern is clear and full, the plate surface stress is small, the strength is stable, suitable for mass production of medium and thick plates, and the cost is controllable.
Cold Rolling Process: Hot-rolled base plate pickling to remove oxide scale → cold rolling finishing → embossing forming → annealing treatment. It has high dimensional accuracy and good surface finish, suitable for thin plates and scenarios with high appearance requirements.
Anti-corrosion Surface Treatment: Carbon steel checkered plates can be treated with hot-dip galvanizing (zinc layer thickness 80–120μm), electrostatic painting and dipping paint, which can effectively delay rust and extend outdoor service life.
V. Mechanical Properties (Taking Q235B as an Example)
Yield Strength: ≥235MPa
Tensile Strength: 370–500MPa
Elongation After Fracture: ≥26%
Anti-slip Coefficient: ≥0.6 in dry environment, ≥0.4 in wet environment, meeting industrial anti-slip safety standards
VI. Core Product Advantages
Anti-slip and Safe: The raised patterns greatly increase the friction of the contact surface, effectively preventing personnel from slipping and materials from shifting, and adapting to high-risk scenarios such as humidity, oil pollution and ice and snow.
High Strength and Load-bearing: The base plate has stable mechanical properties. The Q355B grade can meet the load-bearing requirements of heavy-duty platforms and heavy equipment bases, with anti-deformation and anti-impact properties.
Wear-resistant and Durable: The raised patterns are wear-resistant, and the overall plate is anti-collision and anti-rolling, with a service life far exceeding that of ordinary flat plates.
Easy to Clean and Drain: The gaps between the patterns form natural drainage channels, which are not easy to accumulate water and dust, and daily cleaning and maintenance are simple.
Convenient Processing: It can be cut, bent, welded and drilled, suitable for various non-standard customization, and the construction and installation efficiency is high.
High Cost Performance: Under the same load-bearing strength, it consumes less materials, and the comprehensive procurement and use cost is lower.
VII. Application Scenarios
Industrial Field: Production workshop floors, heavy equipment platforms, escalator steps, maintenance channels, cable trench covers, warehouse shelf planks.
Transportation Field: Truck/trailer compartment floors, ship decks, rail transit steps, airport/station anti-slip walkways.
Construction Field: Building stair treads, external scaffolding planks, roof anti-slip layers, steel structure platforms, municipal walkways.
Other Fields: Cold storage walkways, light-load platforms in sewage treatment plants, construction machinery steps, outdoor landscape anti-slip components.
VIII. Quality Standards and Acceptance Requirements
Dimensional Deviation: Comply with GB/T 33974-2017 standard, and the deviation of thickness, length and width dimensions is within the allowable range of the specification.
Surface Quality: The plate surface has no cracks, scars, folds, edge defects, pattern collapse and other defects; the height difference of patterns on the same plate is ≤0.3mm, and the patterns are regular and uniform.
Material Guarantee: Each batch of products is accompanied by factory certificate and material test report, specifying the grade, specification and mechanical performance indicators.
Anti-corrosion Layer Quality: The coating on the galvanized/painted plate surface is uniform, without missing plating, sagging and peeling, and the adhesion meets the standard.
IX. Packaging, Transportation and Storage
Packaging: Standard steel strip bundling, each bundle weighs 2–5 tons, with product specification, material, batch number and manufacturer marked on the outside.
Transportation: Adopt road/railway transportation, with moisture-proof cushion laid in the carriage to avoid collision deformation and rainwater dampness; custom cut parts are separately packaged for protection.
Storage: Store in a dry and ventilated indoor area or awning, raise the ground to isolate moisture, and avoid long-term outdoor stacking leading to rust; place wooden squares between plates to prevent surface scratches.
X. Purchase and Use Suggestions
Pattern Selection: For most industrial and outdoor scenarios, lentil-shaped pattern is preferred, which has the best anti-slip performance and the strongest versatility.
Thickness Selection: 2.5–3mm for light walkways/decoration; 4–5mm for conventional industrial platforms; 6–8mm and above for heavy-load scenarios.
Anti-corrosion Selection: For outdoor and wet environments, galvanized/painted anti-corrosion carbon steel checkered plates must be selected to extend service life; bare plates can be selected for light-load and dry indoor environments.
Processing Notes: Take protective measures during cutting and welding to avoid burning the anti-corrosion coating by open fire; ensure the plate surface is flat and the force is uniform during installation.
