When you think that your medium-to-large project may need as many as 100,000 fastenings to attach components to structural steel, a faster method for corrosion-resistant fastenings would seem long overdue.
With such volumes, design engineers and contractors working in corrosive environments – like oil & gas, petrochemical, and power & utilities projects – would welcome faster and more efficient ways of fastening components to structural steel. As an additional challenge, the components – such as grating, strut, conduit, cable trays, pipes, electrical boxes, supports for instrumentation panels, etc. – and the fasteners are often exposed to harsh weather, pollution and coastal environments, therefore requiring corrosion protection.
The structural steel may be hot-dip galvanized or coated with paint to help provide adequate corrosion protection depending on the specific environment. However, when fastening components, design engineers and contractors must ensure the corrosion protection of the structural steel is not compromised. The traditional fastening methods used under these conditions include welding, through-bolting and clamping. In this editorial we will compare these with the Hilti methods for fastening on steel and show how Hilti can help save you both time and money.
