The pattern can be a single diamond, bean shaped, or round bean shaped pattern, or it can be appropriately combined from two or more patterns to form a composite pattern board.
Patterns mainly serve as anti slip and decorative elements. The comprehensive effects of anti slip ability, bending resistance, metal saving, and appearance of composite patterned boards are significantly better than those of single patterned boards.
Pattern steel plates are widely used in industries such as shipbuilding, boilers, automobiles, tractors, train carriages, and construction.
Patterned steel plates, due to their protruding edges on the surface, have anti slip properties and can be used as floors, factory escalators, work frame treads, ship decks, car floorboards, etc.
Pattern steel plate is used for the treads of workshops, large equipment or ship walkways and stairs, and is a steel plate with diamond or bean shaped patterns pressed on the surface.
The steel plate is produced from ordinary carbon steel grades 1-3 Class B, with a thickness of 2.5-8 millimeters, a width of 600-1800 millimeters, and a length of 2000-12000 millimeters.
The specifications of patterned steel plates are expressed in terms of basic thickness (excluding the thickness of protrusions), with 10 specifications ranging from 2.5-8 millimeters. Pattern plate steel plate is made of grades 1-3.
The height of the patterned board shall not be less than 0.2 times the thickness of the substrate;
Pattern steel plates shall be delivered according to actual weight or theoretical weight;
Marking example: Made of Q235-A, with dimensions of 4 * 1000 * 4000mm
Round bean shaped checkered steel plate, marked as: Round bean shaped checkered steel plate Q235-A-4 * 1000 * 4000-GB/T 3277-91
Diamond patterned steel plate, marked as: Diamond patterned steel plate B 3-4 * 1000 * 4000-GB 3277-82
Steel plates are delivered in hot-rolled condition; The surface of patterned steel plates shall not have bubbles, scars, cracks, folds, or inclusions, and the steel plates shall not have delamination.
The surface quality is divided into two levels:
Ordinary precision: The surface of the steel plate is allowed to have thin layers of oxide scale, rust, surface roughness caused by the detachment of oxide scale, and other local defects with height or depth exceeding the allowable deviation. Slight burrs and individual marks not exceeding the height of the pattern are allowed on the pattern. The maximum area of a single defect shall not exceed the square of the grain length.
High precision: The surface of the steel plate is allowed to have thin layers of oxide scale, rust, and other local defects with a height or depth not exceeding half of the thickness tolerance.
The pattern is intact and undamaged, and slight burrs with a height not exceeding half of the thickness tolerance are allowed on the pattern.
