What is the difference between PTR and HSS?
The terms may refer to similar hollow sections, but the specified standards, tolerances and properties are not always equivalent. The drawing must be followed.
About Structural Sections
Steel sections for structures, frames and supports, including HSS, square and rectangular tubing, structural pipe and C purlin. Product data brings together sizes, wall thicknesses and weights for project estimating.
Frequently asked questions
Is the tabulated weight exact?
It is a theoretical weight for estimating. Actual weight can vary within manufacturing tolerances.
Who should select a structural section?
The engineer responsible for the structural calculation or design. The catalogue supports comparison but does not replace project engineering.
