LEED (Leadership in Energy & Environmental Design) is a rating system for the design, construction and operation of high performance buildings. LEED is an internationally recognized certification system intended to provide building owners and operators a framework of strategies to increase performance, reduce waste and improve the quality of life.

As a member of the Steel Tube Institute (STI), our products are covered by an Environmental Product Declaration (EPD) for standard, non-fabricated Hollow Structural Sections (HSS) and related products such as standard pipe. This EPD can be used to calculate credits within the LEEDv4 rating system and to meet a growing number of procurement requirements for government and industry. The non-fabricated EPD can be found on the STI website.

As a member of the American Institute of Steel Construction (AISC), our products which have been fabricated are covered under a separate EPD which can be found on the AISC website.
