CITY, STATE and NEAREST LARGE CITY are important because location may control code to be used for design. Standard SAFRAIL™ is UV coated.
Platforms sheltered or inside other structures (INDOORS) will not require wind or snow loads. This answer may be apparent from specifications or drawings, but not so apparent from a telephone request for quote.
Platforms outdoors and ABOVE GROUND (like on buildings) will have larger gust factors for wind conditions.
Platforms in OPEN AND FLAT TERRAIN support HIGHER wind loads and LOWER snow loads. Platforms can be designed for worst case, but may be conservative and unnecessarily uneconomical.
Standard SAFRAIL™ will meet most codes for loading - OSHA, BOCA, UBC, etc. Other codes (for specific contract requirement, etc.) may require higher loads or have specific deflection requirements.
CORROSIVES AND TEMPERATURE may dictate EXTREN® requirements. EXTREN® SERIES may be specified. STANDARD COLOR or OTHER color is needed. HARDWARE will be bolts for structurals, grating clips and bolts, etc. SPECIFY as necessary.
