Pre-galv. hollow section: cold-formed and high-frequency welded pre-galvanized steel strip

The pipe shall be made of pre-galvanized steel conforming to ASTM A446. The coated steel should be cold formed and welded into the tube using a high-frequency induction welding process that can form a weld that is stronger than the base material. The external coating damaged during welding should be repaired by metallization (spraying molten zinc wire). The internal welding area damaged during welding shall be unprotected.

The zinc coating on the steel plate shall comply with ASTM A525 G90 and G120 grades. The total weight of zinc on the inner and outer surfaces should be between 0.90 oz / sq ft (or 0.45 oz / sq ft per side) to 1.20 oz / sq ft (or 0.60 oz / sq ft per side). These coating weights do not apply to the internal welding area.
