VANTRUNK – Shallow Channel Corrugated Steel Framework

Technical Specifications

• Steel with a minimum yield strength of 280 N/mm².

• Beams are assumed to be simply supported.

• Load and deflection are calculated using a safety factor of 1.6 and a permissible stress of 175 N/mm².

• Results are based on pre-galvanized steel; hot-dip galvanizing will reduce stresses from the heat treatment and lower the tabulated load values by approximately 18%.

• Beam loads are calculated in accordance with BS5950, measured from column face to effective length.

• Tables show:

  1. Maximum safe working load

  2. Load producing a deflection of 1/200

  3. Load producing a deflection of 1/360
     – The choice of deflection criteria is at the discretion of the installation designer.

• Applies equally to both point loads and uniformly distributed loads (UDL).
