特殊形鋼グレーチング
Special-shaped steel gratings are manufactured into various irregular configurations based on customers’ specific requirements. Common forms include corner-cut, hole-cut, arc-cut, and fan-shaped designs. This customization eliminates the need for on-site secondary cutting upon delivery, making construction and installation more efficient and straightforward while preventing damage to the galvanized layer that would occur with on-site cutting. Special-shaped steel gratings are defined in relation to rectangular steel gratings.

Special Shaped Steel Grating Shapes
Characteristics of Special Shaped Steel Grating
Light weight: Compared with traditional steel plate materials, special-shaped steel grating is lighter and easier to carry and install.
High strength: Due to the special structure of the steel bar, the special-shaped steel grating has high compressive strength and bending strength and can withstand large loads.
Corrosion resistance: The surface of the special-shaped steel grating is hot-dip galvanized or sprayed, and has good corrosion resistance and can be used in humid and corrosive environments.
Good looking: The surface of the special-shaped steel grating has been treated to have a bright and flat surface, which is beautiful and can enhance the overall image of the building.
