Frequently Asked Questions (FAQ):

Q: What is the primary difference between forged and pressed steel scaffolding clamps?

A: Forged steel clamps (e.g., drop-forged) are manufactured by shaping hot steel under high pressure, resulting in a continuous grain flow that enhances strength, durability, and fatigue resistance, making them ideal for heavy-duty applications. Pressed steel clamps are formed by stamping and welding steel sheets, which are lighter and suitable for lighter-duty or less critical applications where initial cost is a primary concern. Both meet relevant safety standards but differ in ultimate performance and lifespan.

Q: How does hot-dip galvanization compare to electro-galvanization for corrosion protection?

A: Hot-dip galvanization involves submerging the clamp in molten zinc, creating a thick, metallurgical bond that provides superior, long-term corrosion resistance (typically 60-80 microns coating) and excellent abrasion protection, ideal for harsh outdoor environments. Electro-galvanization (zinc plating) applies a thinner zinc coating (8-12 microns) electrolytically, offering good protection for less aggressive environments and a smoother, more aesthetic finish.
