Manufacturing location for Duraclad
Sheet lengths: Steelspan 900 is custom run to order. Where long sheets are used consideration must be given to:
- special transportation licences for sheet lengths over 25m
- site access for special lifting equipment
- fixing techniques to accommodate thermal expansion.
