Door Leaf

A 45mm thick, flush edged 18g zinc coated steel leaf with a bonded non-fibrous honeycomb core selected for torsional load performance. 

The vertical edges of the skins are folded to create a full height, bevelled edge with interlocking seam for increased panel strength and rigidity.

The void between the two skins is in-filled with a bonded honeycomb core material, selected for its compression & torsional load performance.

The hinging edge is reinforced by steel hinge mounting plates welded within the leaf, and the lock mechanism is installed within an inner enclosure to facilitate is removal for future maintenance or replacement.

On externally located double doors an astragal is fitted to one leaf to ensure positive sealing at the centre.

Frame

Galvanized steel folded to form a double or single rebate profile.

Frame sections are pressed from galvanized steel to form a double (standard) or single rebate profile. Headers are profiled to form a smooth, butt joint with the full height vertical posts and headers include bolt fixing for positive engagement.

Uprights are reinforced with steel plates at all hinge & lock points.

Shallow depth thresholds are available at extra cost, either as folded steel or extruded aluminium sections.

Frames are arranged for bolt fixing to any suitable opening structure.

Vision Panels

Vision panels are available in various standard sizes, glazed with CERTIFIRE approved glass and gaskets.

Seals

A variety of approved compression and wiper seals are available, fitted into the frames to leaf rebate, between the leading edges of double door leaves and in the bottom edge of door leaves.

Finish

Door leaves and frames receive one coat of self etching primer, as standard, for site painting. Alternatively, they are supplied factory finished in any standard RAL or BS4800 colour. Specialist paint systems to suit coastal/chemical environments and foodsafe applications are also available.

Maintenance Packages

Planned preventative maintenance

See our maintenance section or contact us for more information. Guardian's repair and maintenance services and engineers are accredited to the DHF's TS004 Repairs and Maintenance standard.

It is a legal requirement - as failure to show evidence of maintenance could mean prohibition & enforcement notices being served and fines up to £5000 and imprisonment for 2 years. 'Safety In Use' - the New European CEN Standards legislation - states that all types of door should be maintained in an efficient state, in efficient working order and in good repair. For further clarification visit www.dhfonline.org.uk.

Routine maintenance prolongs the operational life of the installation and ensures that the installation is kept in good working order - helping to prevent accidents and damage which in turn results in down time, effecting work flow, productivity and resulting in loss of revenue. It assists in identifying potential problems which can easily be rectified.
