Considerations such as weight, long-term durability, structural stability, and consistency of quality will help define the right support structure for the job.

  • Requires the mining of iron ore, coal, limestone, magnesium, and other trace elements
  • To produce steel, iron must first be refined from raw ore; the iron ore, together with limestone and coke (heat-distilled coal) are loaded into a blast furnace; hot air and flames are used to melt the materials
  • Most steel contains a minimum of 25% recycled steel and is 100% recyclable; good indoor air quality (IAQ) is promoted because steel does not emit volatile organic compounds (VOCs)
  • Derived from bauxite ore
  • Requires a large amount of raw material to produce a small amount of final product
  • Aluminum manufacturing is a large consumer of electricity
  • Byproduct of the smelting process contains fluoride and chlorine and must be disposed of as hazardous waste
  • Lightweight, corrosion resistant, and low maintenance
  • Recyclable
  • Harvested material most commonly used in buildings and building products
  • Products such as plywood, particleboard, and paper are commonly used throughout the construction industry
  • Sustainable forestry practices will include a professionally administered forestry management plan in which timber growth equals or exceeds harvesting rates in both quantity and quality
