HDG Floor Grating and Grating Stair Tread for Offshore Application

Hot dip galvanized floor grating and hot dip galvanized grating stair tread for offshore application.

• Hot dip galvanized floor grating (width × length), mm: 1005 × 600 LB.
• Hot dip galvanized floor grating (width × length), mm: 1005 × 900 LB.
• Hot dip galvanized floor grating (width × length), mm: 1005 × 1200 LB.
• Hot dip galvanized grating stair tread 215 × 600 mm with accessories.
• Hot dip galvanized grating stair tread 245 × 1000 mm with accessories.

Due to the tropical and marine environmental conditions and working conditions of offshore objectives, below two items must be considered.

• The bar gratings have strong non-slip characteristics due to oily and slip surface of floors, walkways on offshore objectives during application.
• The gratings must be enhanced anti-corrosion characteristics due to high corrosive conditions on offshore objectives.
