Steel Portal Frames

  • All portal frames are insulated with King-spam insulation as standard
  • All portal frames are galvanised as standard with a high quality powder coating system of two coats, including special ST-RAL numbers.
  • Where portal frames are planned to be covered by pressings instead of powder coating, the steel is galvanised as standard to prevent any rust.
  • Standard portal frame sizes are fixed with 8.8 grade M10 thunderbolts and 8.8 grade M10C/S bolts.
  • Tonnage Weight specifications are available with structural calculations
  • Calculations of size and weight may exceed standard fixings so structural calculations are worked out in Newton’s per tonne which will indicate that larger fixings are required.
  • We have a unique and effective way of fixing the portal frames together by drilling and tapping the steel lugs which is our own design, then we use countersunk head-bolts to fix. A substance call Loctite can also be used on request. A chemical anchor resin is also used when necessary.
  • Base plates as standard are worked out from calculations that are a minimum of 8mm thick with a minimum of five fixing points to the pad stone. We also use calculations for the size and depth of the pad stone.
  • Our team of portal frame installers not only have the knowledge and experience in steel work but also general building work as portal frame installations commonly take place in a residential property. We never damage brickwork and our team ensure work is carried out with the utmost courtesy.
