4. FRAMING




General Switchgear & Controls Ltd.provides two type of framing for steelbuilding system.

Truss FrameThis type of design is employed forlarger buildings and when equipmentinstalled is heavy and a single point liftwith spreader bars is required. In thisdesign the primary trusses spanningthe width of the building are spaced ona pre-determined bay length andsupport the secondary structuralmembers and walls.

Self-FramingThe majority of our buildings aredesigned using self-framing, selfsupporting method. This type ofbuilding utilizes the cladding asprimary load bearing for the roof and/or wall elements, also functioning as aweather barrier. It may be either asingle or multi-span structure.

5. STRUCTURE BASE

The base frame is designed for thestatic and dynamic load requirements.Welded bracing provides adequatestrength for handling the completeassembly with the base lifting lugs.The base frame consists of structuralsteel, A36 channel or I-beam and

angled structural sections as requiredmeeting the design load conditions. Theunderside of the base frame is coatedwith a corrosion resistant undercoatingfor protection against corrosion oralternatively hot dipped galvanized.

The base is designed for installation onconcrete pier or pad provided bycustomer. Concrete Slab, crushed rockor other kinds of foundation are alsoacceptable depending on the site soilcondition. Removable lifting lugs areprovided on the base for lifting/handling.Single point lifting of the completedbuilding is possible by using slings andspreader bar.

6. FLOOR

The floor plate is constructed from 3/16or ¼ inch steel plate welded to the mainand cross member of the base frameand is designed to support heavyequipment and floor loads. Removablecover plates are provided to gain accessat the bottom of the base frame, ifrequired.The floor plate is designed for afloor live load of 50 PSF to 250PSF witha concentrated load of 2,000lbs.Thefloor is finished with anti skid paint as astandard. Checkered and anti-skid floorplates can also be provided, if required.




7. WALLS

The exterior walls are made from 11gauge sheet steel. The wall sections areuniquely formed at the sides, top andbottom to provide the required strength &rigidity without the use of a framedstructure. The wall frames are boltedinside to the base frame; roof andadjacent wall frame and thus provide aclean & smooth external appearance withno fastening visible from outside.

A weatherproof gasket is providedbetween the panels, base frame and roofto provide complete weather sealprotection for long service and lowmaintenance.

The walls are designed to withstand awind loading of 125 miles per hour.
