How to Maintain building?

RSSLLP recommends that you follow our simple maintenance recommendations for steel buildings. By doing so, you will enhance the life of your investment. Frequency of maintenance is dependent upon the environmental zone in which the building is located.

Safety Notes for Roof maintenance

  • Extreme caution should be exercised when working on roofs.
  • Professional maintenance staff shall be used for maintenance works.
  • Access ladders shall reach at least one meter above the step off point.
  • Ladders shall be secured to the building, and shall be on a firm base.
  • Do not step on skylights.
  • When walking on the roof, step in the valleys of the panel, not on the ribs.
  • Whenever possible, walk on the purlin line, (screw line).
  • Areas of roof subject to frequent access shall be protected by temporary or permanent walkways.

Exterior Maintenance Procedure

  • Preventive maintenance shall commence immediately after a project is erected or modified.
  • Debris and small items such as screws, pop rivets, drill bits, or any ferrous objects shall be removed by sweeping with a soft nylon brush. Large items such as sheet metal cut-off shall be removed by hand to avoid damaging the surface of the roof panels. Such debris shall be removed after any trade, (e.g. electricians, plumbers, air conditioning technicians and steel erectors) has worked on the roof.
  • Sand and dust retain salt and moisture, which will eventually breakdown the paint and zinc layers, resulting in corrosion of the base metal. Sand and dust shall be removed by washing with clean potable water and a soft nylon brush, working from the highest point to the lowest, followed by a final rinse using a hose and clean potable water.
  • The most vulnerable areas of the building are gutters, roof sheets, sheltered areas under eaves or canopies, and upper portions of walls or roof extensions.
  • For buildings located in high pollution industrial areas, or close to marine environments, water alone may not be sufficient to remove saline deposits that have become encrusted on the panels. In such cases, a mild detergent should be added to the initial washing water. Panels shall be washed with the mild detergent solution and a soft nylon brush. A final rinse with clean potable water should follow. Oil, grease, tar, wax, or similar substances can be removed with mineral spirits, followed by a detergent solution and a clean potable water rinse.
  • Do not use caustic or abrasive cleaners, they may damage the paint and zinc layers.
  • Ground level shall be maintained at least 150 mm below the base of the wall panel.
  • Accumulations of wind blown sand shall be removed. Plants and shrubs surrounding the building shall not touch the wall panel; they may scratch the painted panels.
  • Eave gutters and valley gutters shall be thoroughly cleaned with a mild detergent solution and a soft nylon brush, followed by a rinse of clean potable water.
  • Downspouts shall be clear of blockage, and the downspout discharge shall have adequate drainage area.
Minor damage to sheeting or trims shall be repaired as follows.
  • Lightly abrade the affected area.
  • If base metal is exposed, apply one coat of zinc chromate primer.
  • Apply one coat of matching touch-up paint.
Equipment, which is located through or adjacent to roof or wall panels, may cause moisture build up on or near the panel. The following conditions should be avoided.
  • Water run-off from air conditioning units.
  • Open water storage tanks adjacent to panels.
  • Steam outlets.
  • Acid storage.
  • Copper pipes fastened to steel panels.

Maintenance of Accessories

Power Vents

Clean fan blades to remove build-up of dust and dirt.

Buildings with Cranes

Every 6 months check that all bracing is tight.

Check that all high strength bolts in the crane beams and main frame connections are tight.

When maintaining overhead crane runways, immobilize the crane before commencement of work.

Record of Maintenance

A Periodic Maintenance Log Book should be kept by you. All maintenance dates should be recorded and signed by your maintenance staff.

How to store material before erection?

These products were dispatched from our factory in good condition. To maintain this condition, we recommend that the bundles of sheets, purlins or channels are stored 150mm clear of the ground, with a slope of 1:25, to allow for water drainage. Cover the stack with a waterproof cover, leaving the ends open to allow for air circulation.

Upon receipt of materials, it is recommended that bundles of panels be checked. If any water is entrapped between sheets, the sheets should be carefully dried, and then re-stacked allowing for air circulation.

It is recommended that panels be installed as soon as possible after delivery. Extended site storage is not recommended.

RSSLLP accepts no responsibility for staining of Galvanized, Galvalume or deterioration of Painted products due to incorrect site storage.

Why timber should not contact to galvanized steel or galvalume steel?

Green timber should not come into contact with galvanized steel or Galvalume coated steel, due to acidic substances in the timber which have a corrosive effect on the metallic coating. The use of kiln dried or appropriate dried timber species is therefore recommended for any situation where intimate contact between the metallic coated steel and timber is considered.

Copper/chrome/arsenic (CCA) timber cladding used in a run-off situation, can result in a corrosive leachate from the timber containing copper, which if it contacts galvanized, or galvalume steel will promote corrosion.

If CCA treated timbers must be used then the timber and/or steelwork should be sealed by fully painting the material prior to installation.

Are PEB suitable for all kinds of weather conditions?

Yes, Rishikesh can supply buildings for a range of weather conditions including snow conditions, high desert temperatures, high humidity, proximity to sea, heavy rainfall, cyclone wind speeds, seismic loads, etc. Based on ambient conditions at the site and building usage, we design and manufacture the building to the specified requirements.

How much saving in foundations?

The saving would be basically due to less number of column foundations due to large spans and bay spacing plus reduction in column reactions due to less dead load of steel. It is not possible to accurately quantify the cost savings as it would vary by type of project. Pre-engineered buildings utilize pierced (column) beam as a general rule, which results in lighter foundations.

Is it possible to dismantle the building and reconstruct it at another place ? What will be the cost for the same?

Yes, it is possible to dismantle and rebuild at a new location. The costs would have to be worked out on a case-by-case basis depending on size, complexity and distance to new location.
