| − | ;DESCRIPTION
| |
| − |
| |
| − | VicWest RIB ROOF is a 450 mm (18") wide by 50 mm (2") deep by .61 mm (0.024") thick Exposed Metal Roof Panel providing a 225 mm (9") visual module. The panel can be applied to solid wood or steel decks with or without insulation. The panel uses a patented internal clip system for attachment to the sub-straight members and thermal expansion capabilities. RIB ROOF side seams snap together with or without side seam sealants to form a strong interlock without the use of a mechanical seaming device. Panels are available in galvanized steel, galvalume steel, Modified Silicone Polyester and Kynar Metallic painted finishes. Normal sheet lengths range between 1.2 m (4') to 18 m (60') and lap joint details are available where longer roof lengths are required.

| |
| − |
| |
| − | :The roofing assembly / material information published in the <b>RCABC <i>Roofing Practices Manual</i></b> DOES NOT represent a complete set of the manufacturer's published data, nor does it represent a fully detailed specification. The preparation of a detailed specification is the responsibility of the design authority and that authority should contact the manufacturer’s technical representative for full technical, specification and product application information.
| |
| − |

| |
| − |
| |
| − | 2.1 <u>MATERIALS</u>
| |

| |
| − | :.2 Manufacturer shall be a member of Good Standing with the Canadian Sheet Steel Building Institute (CSSBI) and the Roofing Contractors Association of British Columbia (RCABC).
| |
| − | :.3 Fabricated from ASTM A 653 / A 653 M SQ (structural quality) minimum grade 33 galvanized steel with a zinc coating of Z275 galvanized as designated by ASTM A653 or ASTM A 792 / A 792M 55% Aluminium – Zinc Alloy Coated steel with an Alloy coating of AZ 150 as designated by ASTM A 792.
| |
| − |
| |
| − | :.4 Profile designation shall be VicWest RIB ROOF with a minimum steel core thickness of 0.61 mm (0.024").
| |
| − |
| |
| − | :.5 Panel clips used to attach the panels to sold wood, plywood or steel decks are a one piece assembly 62.5 mm (2½") long by 225 mm (9") wide by 50 mm (2") high with one end formed to engage the male side of the panel and the other end formed to engage the centre rib of the adjacent panel. Rib Roof Clips are fabricated from 1.22 mm (0.048") Z-275 galvanized or AZ-150 Galvalume ASTM A 653 steel.
| |
| − |
| |
| − | :.6 Pre-finished sheet steel, in addition to meeting the requirements of 2.1.3, shall have a 2-coat (minimum) Silicone Modified Polyester Paint or Kynar System, factory applied, cured by baking, using colours of proven durability for exterior exposure.
| |
| − | :.7 Subject to specification Polybutylene Mastic tape caulking of suitable thickness and width will be supplied with the cladding panels for the sealing of side and end lap joints.

| |
| − | ;PART 3 - EXECUTION
| |
| − |
| |
| − | 3.1 <u>STORAGE OF MATERIAL ON SITE</u>
| |
| − | :.1 Steel sheet roof cladding shall normally be delivered to the jobsite as required for installation, but if site storage becomes necessary, suitable storage areas shall be provided by the general contractor as close to the building site as is practical. Preferably this storage shall be under cover.
| |
| − |
| |
| − | :.2 When outdoor storage is unavoidable:
| |
| − | ::a) Use good quality covers, other than plastic, loosely shrouded over stacks and firmly anchored to prevent wind blow-off.
| |
| − | ::b) Tilt bundles for drainage.
| |
| − | ::c) Ventilate bundles but do not allow the entry of wind driven precipitation.
| |
| − | ::d) Block bundles off ground for effective ventilation,
| |
| − | ::e) Block bundles to prevent sagging.
| |
| − | ::f) Store away from all chemically aggressive substances (e.g. salt, cement, fertilizer), away from all materials that could contaminate the surface (e.g. diesel oil, paint, grease) and away from all traffic to avoid physical damage.
| |
| − |
| |
| − | :.3 Moisture can cause wet storage staining of metallic coated and pre-finished material and usually occurs as a result of:
| |
| − | ::a) Condensation from high humidity and / or temperature cycling.
| |
| − | ::b) Wet shipping conditions.
| |
| − | ::c) Wind driven rain penetration (outdoor storage).
| |
| − |
| |
| − | :The usual progression is from water staining to unsightly white staining (dark grey to dull black on aluminum-zinc alloy coated sheet) to red rust. On material where wet storage staining has occurred, it should be noted that, except for aesthetic considerations, a nominal amount of staining is not detrimental to the functioning of the product.
| |
| − |
| |
| − | 3.2 <u>INSTALLATION</u>
| |
| − |
| |
| − | :.1 All installation work shall be carried out by trained erection crews all in accordance with the fabricator’s and these specifications.
| |
| − | :.2 Examine and obtain all necessary measurements of previously executed work which may effect the work of this Division.
| |
| − | :.3 Exercise care in unpacking, moving, storing, handling and placing panels to prevent damage likely to impact the adequacy or appearance of the material in the finished structure.
| |
| − | :.4 Sheet steel roof cladding shall be installed in the longest lengths possible and shall be adjusted to final. position before being permanently fastened to structural supports
| |
| − |
| |
| − | :.5 Rib Roof Clips shall be installed at a maximum space of 600 mm (24") for roof cladding fabricated from grade 230 steel.
| |
| − |
| |
| − | :.6 The clips shall be fastened to wood or plywood decks with 2 - #12-11 x 25 mm (1") pan-head wood screws. For steel decks use 2 - #12-14 x 25 mm (1") self-drilling pan-head sheet metal screws with a #1 drill tip. The screws shall be applied to the centre pre-punched holes adjacent to each clip vertical leg.
| |
| − |
| |
| − | :.7 For insulated roof systems insulation shall be a rigid foam board with a compressive strength of a minimum 20 psi. A metal bearing plate 150 mm (6") x 230 mm (9") x 0.61 mm (.024") shall be installed under each clip on top of the foam insulation. Screw lengths shall be extended to suit insulation thickness and shall be placed in the clip pilot holes and be drilled through the bearing plate, insulation and screw into the sold wood or steel deck.
| |
| − |
| |
| − | :.8 End laps shall be located over supports. Minimum end laps shall be:
| |
| − | ::a) 100 mm (4") for roof cladding used on roofs with a slope of 1:3 (4" in 12") or more;
| |
| − | ::b) as per fabricator’s specifications for roofs sloping less than 1:3 (4" in 12").
| |
| − |
| |
| − | ::End laps on roofs shall be sealed with the recommended continuous sealant tape and / or caulking compounds.
| |
| − |
| |
| − | :.9 Subject to specification, side laps shall be sealed with continuous lengths of taped caulking.
| |
| − |
| |
| − | :.10 When cutting or drilling pre-finished material, care shall be exercised to ensure that cuttings do not remain to rust on exposed pre-finished surfaces. Where practical, cutting and drilling shall be conducted so that cuttings do not strike or accumulate on exposed cladding surfaces.
| |
| − |
| |
| − | :.11 This contractor shall remove all cuttings, grime and dirt from the cladding by dry wiping the panels as the material is erected.
