STRUCTURAL TRADE LINK
STL is a construction platform built for engineers and contractors to solve problems and find the materials they need. Use TOOL BOX for engineering calculators, section properties, rigging calculations, and other technical resources, then move into NETWORK to find suppliers for structural steel, rigging, bolts, and other construction hardware based on region, distance, inventory type, and more.
The STL Mission
STL is designed to close the gap between engineering and procurement by streamlining the process from identifying what you need to finding who can supply it. By connecting TOOL BOX directly with NETWORK, STL helps users move from solving a problem to identifying potential suppliers without starting the sourcing process from scratch.
