Steel Plate for High Buildings

In Pre-engineered Pre-fabricated steel houses the maintenance area is the roofing & cladding.

Steel roofing & side wall cladding requires minimum maintenance.  The roof should be inspected immediately after installation to check if cleaning of the roof has been carried out fully.  It is very often seen that the drilled out metal and debris are not swept away.  These can act as initiators of corrosion and lead to premature failures.

In case of cement particle board walls painting required every 3-4 years.

Installed roofing must be inspected atleast once a year.  Any exposed metal that can rust or has rusted should be painted.  Leaves, branches, and trash should be removed from gutters, at ridge caps and in corners.  Also watch out for discharge from industrial stacks, and particulate matter and high sulphur exhaust from space heaters which could get piled up.

Roof top ancillaries and air conditoner supports, drains and housing should be checked.  Particular attention should be paid to add-on roof ancillaries that create new roof penetrations. Roof-top air conditioners should be installed on curbs designed to avoid ponding water.  Condensate from air – conditioning and refrigeration equipment should never be allowed to drain directly on to the roof panels.  The drainage contains ions from condenser coils that accelerate corrosion.

In the event of a roof leak, do not indiscriminately plaster the suspected leak area with tar or asphalt or use repair tape.  Water can collect under the repair material causing corrosion.  Instead, have an experienced roofing foreman locate the leak, identify its cause and properly repair the roof.
