Structural steel used in bridges, industrial plants, high-rise buildings, offshore platforms, transmission towers, and heavy engineering projects must meet demanding standards of cleanliness, strength, and surface preparation quality. Shot blasting plays a central role in ensuring steel components exhibit the required performance in terms of corrosion resistance, coating adhesion, weld integrity, and dimensional accuracy.
At Airo Shot Blast Equipments, we design advanced shot blasting equipments that address all critical requirements of modern structural steel fabrication. Our systems provide consistent surface cleaning, high-speed scale removal, and uniform roughness generation, ensuring steel is fully prepared for painting, galvanizing, cutting, or welding.
Raw structural steel often contains:
Shot blasting removes these contaminants efficiently, producing a uniform metal surface that complies with global surface preparation standards such as SA 2.5 and SA 3.
Protective coatings—such as epoxy paints, zinc-rich primers, and intumescent fireproof coatings—require a controlled anchor profile. Shot blasting ensures:
