 Primary Built-up Members & Primary Framing Systems |
|
| The Primary Framing System comprises of built-up welded Hot-rolled I shaped Columns and Rafters. The framing is prepared at Devashish plant and is required to only fitted with bolts in order to assemble at the site. This structure is responsible for transfer of complete building load to the foundations. Primary Framing System consists of: |
 |
 |
| Typical Rafter |
Typical Column |
|
| |
| Endwall Frames |
| Made of built-up welded Hot Rolled Columns and Rafters. The Frames of Columns and Rafters are supported by connection bolts, anchor bolts and wind bracing. |
|
| Intermediate Frames |
| Made up of built-up welded Hot Rolled Columns and Rafters. The Frames of Columns and Rafters are supported by flange bracings, connection bolts and anchor bolts. |
|
| Wind Bracings |
| They provide longitudinal stability to the building. This consists of High grade steel bracing provided in the roof and side walls in one or more bay depending on loading of the building and its length. If necessary, cross bracings can be effectively replaced by wind portal frames or by fixed base wind columns located adjacent and connected to the main frame columns. |
|
|
| Given below are the commonly used Primary Framing Systems. All the Primary Frames shown herein are symmetrical about the ridge line. Frame asymmetrical about the ridge line, unequal width module and other non-standard frames are also possible. |

| The Secondary Framing System functions to support and bear the load of Roofing and Cladding and transfer its load to the Primary Framing. The Secondary Framing includes the Roof Purlin, Wall Girts, Clits and miscellaneous items. |
|
| Roof Purlins |
These are cold formed Z profiles generally 200 mm to 300 mm deep made from 1.5 mm to 2.5 mm thick 245 mpa/345 mpa strength steel. Purlins are fixed to the top flange of the rafter with a clip bolted to the rafter and the purlin web bolted to the clip.
|
|
| Wall Girts |
These are cold formed Z profiles generally 200 mm to 300 mm deep made from 1.5 mm to 2.5 mm thick 245 mpa/345 mpa strength steel. They are fixed to the outer flange of the side wall columns.
|
|
| Eave Strut |
| These are cold formed Z or C profiles generally 200 mm to 300 mm deep made from 1.5 mm to 2.5 mm thick 245 mpa/345 mpa strength steel. These are fixed to the outer flange of the outer side wall column with clips bolted to the column and the eave strut bottom flange bolted to the clip. |
