Columns and rafters of rigid frames are tapered built-up “I" sections. Interior columns of multi-span frames may be square tube sections.

All rigid frame connections are bolted. Columns and rafters are provided with welded end plates for anchoring to  foundations and for member-to-member at tachment .Pre-punched holes or welded clips are provided for attachment of purlins and girts, bracing, and other components.

Load bearing Òpost-and-beamÓ (P&B) end frames may be
constructed from cold-formed channels, hot rolled sections or built-up welded plate sections, as required.

Purlins and girts are pre-punched cold-formed ÒZÓ shaped sections, 200 mm in depth with stiffened flanges.

Eave struts are pre-punched cold-formed ÒCÓ shaped sections 180 mm in depth with 85 mm stiffened flanges. The eave strut serves as a longitudinal structural bracing member in addition to acting as a transition point for wall and roof sheeting.

Panels (roof and wall) are roll formed to the maximum practical  ength (generally 9000 mm) to minimize end laps in the field.

The standard roof and wall panel. It is a roll formed panel having 4 major high ribs and 4 minor ribs. The panel covers a width of 1000 mm. The lapped major rib has a siphon break to prevent capillaric intrusion of water at the side lap. The panel has an extended bearing leg to provide stiffening during installation.

Roof panels have a minimum end lap of 150 mm over purlins and are fully protected from siphon action by end lap mastic.

Wall panels have the same side lapping as the roof panels. No side or end lap mastic is required.

Tempcon panels are factory injected sandwich panels. They comprise of a hard polyurethane foam core between two single skin panels. The rigid foam core has a density of approximately 40 kg/m3. The standard roof Tempcon panel is the Tempcon Hi- Rib (TCSP) panel. The outer panel is the standard Profile "S" panel, described in section 1.4.7. The inner panel is a Profile "T" panel, which is a flat panel that has ten equal ribs each 50 mm wide. The standard wall Tempcon panel is the Temcpon Lo-Rib (TCTP) panel. Both the outer and inner panels of the TCTP panel are Profile "T" panels. All Tempcon panels cover a width of 1000mm.

Eave gutters are supplied in lengths of 6000 mm. They are cold-formed to a profiled cross-section that is 170 mm wide x 154 mm high.

Downspouts for eave gutters are supplied in lengths up to 9000 mm to minimize splicing. They are cold-formed to a ribbed rectangular cross section 105 mm wide x 73 mm deep.

Valley gutters are supplied in maximum lengths of 4500mm. They are cold-formed in two standard types. Type I is 370 mm wide x 190 mm high. Type II is 400 mm wide x 190 mm high.

Downspouts for valley gutters in Multi-Gable (MG) buildings are PVC pipes supplied in three sizes; 110 mm, 160 mm and 200 mm (inside diameter). Fiberglass outlets connecting the valley gutter to the downspouts are also supplied.

Diagonal bracing that provides longitudinal stability against wind, seismic or other forces, is attached to the web of the rigid frame near the outer flange of columns and rafters. The standard diagonal bracing is a galvanized steel 7-wire strand cable having an eye bolt with an adjusting nut and hillside washer at each end. Solid round bars or hot rolled angles may be used as required by design.

Flange braces, in the form of angles, are provided to stabilize the interior flanges of rigid frame rafters and columns at certain purlin and girt locations.

Base angles shall be provided in fully sheeted walls in 6000 mm length to attach the wall panel to the concrete slab. The concrete floor slab is required to have a 40 mm x 40 mm notch at the perimeter (below the finished floor level) to accommodate the bottom of the wall panel to revent ingress of dust and water. The base angle shall be a light gauge bent plate.
