Perforated metal facade panels with square holes are installed on the exterior wall.

Punching skid plate

Different from ordinary ladder, our safety grating ladder rungs surface has rows of dimply holes for slip resistance. The hole shapes are available in diamond grip, o-grip and traction tread. Featured with good bearing capacity, safety grating ladder rungs are ideally for creating an ascending passageway to rooftops, large machinery & equipment, water towers, wastewater tanks, platforms or loading docks.

  • Designed with highly precise and uniform pattern.

  • Resistant to slip in all weather conditions.

  • Grips soles securely in all directions.

    • Where to use? Outdoor or indoor?

    • Work environment? What are the risk factors for falls?

    • Slip resistance level requirement.

    • Corrosion protection level requirements.

    • Need to be easy to install, operate and maintenance.

    • Material strength.


    Pre-galvanized carbon steel

    Galvanizing process can effectively prevent steel corrosion and rust, so as to prolong the service life of steel. (ASTM A-924-G90)

    HRPO carbon steel

    Hot Rolled Pickled and Oiled (HRPO) steel is produced to protect the steel from rust and corrosion. This type of material is good for fabricating, welding, bending and cold forming. Finished products have a clean and flat surface that can be used in a variety of applications. (ASTM A-1011 HRPO)


    We adopt 5052-H32 aluminum as material. Its main alloying element is magnesium, which has excellent formability, corrosion resistance, weldability and medium strength. The load capacity of 5052-H32 aluminum can be up to 0.5 lbs./ft.

    Stainless steel

    Stainless steel has good corrosion resistance, heat resistance, low temperature strength and mechanical properties. It also has good hot workability such as stamping and bending.

  • Pattern Design

    There are six main patterns of perforated metal panels.
    • Above hole shapes can be arrayed in straight or staggered method.
    • Different types of ornaments like writings, company logos or any other pattern are available.
    • Except for general patterns, ornamental type are also available.
