A steel plate with a raised (or concave) pattern on the surface.

The patterned steel plate, also known as the mesh steel plate, is a steel plate with a diamond shape or protruded edge on its surface.
The pattern can be a single diamond shape, lentil shape or round bean shape, or two or more patterns can be appropriately combined into a combined pattern plate.

Characteristic of pattern plate

The pattern mainly plays the role of anti-slip and decoration. The combined pattern board’s anti-slip ability, bending ability, metal saving and appearance are obviously better than the single pattern board.
Patterned steel plates are widely used in shipbuilding, boilers, automobiles, tractors, railway cars and construction industries.
Because the surface of the patterned steel plate has a protruding edge, it has a non-slip effect, and can be used as the floor, the factory ladder, the work frame pedal, the ship deck, the car bottom plate, etc.

Pattern plate production technology

The patterned steel plate is used for the pedals of walkways and stairs of workshops, large equipment or ships, and is a steel plate with a diamond or lentil pattern pressed out on the surface.
The steel plate is produced from ordinary carbon steel 1-3 Class B steel, with a thickness of 2.5-8 mm, a width of 600-1800 mm, and a length of 2000-12000 mm.
The specifications of the pattern steel plate are indicated by the basic thickness (regardless of the thickness of the protruding edge), and there are 10 specifications of 2.5-8 mm. Pattern plate steel plate with 1-3.
The height of the pattern plate is not less than 0.2 times the thickness of the substrate;

Delivery standard of pattern plate

Mark example: Made of Q235-A, size 410004000mm.
Round bean pattern steel plate, marked as: round bean pattern steel plate Q235-A-410004000-GB/T 3277-91
Argyle steel plate, which is marked as: Argyle steel plate B 3-410004000-GB 3277-82
The steel plate is delivered in hot rolled condition; The surface of the patterned steel plate shall not have bubbles, scars, cracks, folds and inclusions, and the steel plate shall not be layered.
Surface quality is divided into two levels:
Ordinary accuracy: The surface of the steel plate is allowed to have a thin layer of iron oxide, rust, surface roughness caused by the loss of iron oxide, and other local defects whose height or depth exceeds the allowable deviation. The pattern is allowed to have non-obvious burrs and individual marks that do not exceed the height of the pattern. The maximum area of a single defect does not exceed the square of the grain length.
High precision: the surface of the steel plate is allowed to have a thin layer of oxide, rust and other local defects with a height or depth not exceeding half of the thickness tolerance.
The pattern is intact, and the height of the pattern is allowed to be no more than half of the thickness tolerance of the local slight burrs.
