DESCRIPTION

VicWest SNAP RIB is a 300 mm (12") wide by 25 mm (1") deep by .61 mm (0.024") thick Exposed Metal Roof Panel. The panel can be applied to solid wood or steel decks with or without insulation. The panel can be supplied with or without 6mm (1/4") x 18 mm (3/4") screw slots for thermal expansion capabilities. SNAP RIB is attached to the substrate deck with hidden pancake head fasteners and the 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.

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 INSTALLATION

Note to Specifier: A certain amount of waviness called ‘oil canning’ is inherent in any product manufactured from coiled sheet material. The amount of ‘oil canning’ can vary due to several factors: uneven substrates, the width of the panel, weather conditions, etc. Minor ‘oil canning’ of a panel does not affect its structural integrity and is not sufficient cause for rejection.

3.03 ADJUSTING AND CLEANING

A. Repair panels with minor damage.

B. Remove panels damaged beyond repair and replace with new panels to match adjacent undamaged panels.

C. Clean exposed panel surfaces promptly after installation in accordance with recommendations of panel and coating manufacturers.

D. Remove protective film immediately after installation.

Note: Portable rollformers are light duty machines with fewer forming stations than manufacturers' factory equipment. Garland suggests avoiding the use of these machines in all circumstances. Portable rollformers can induce significant oil canning and other poor performance and aesthetic qualities in the panels. For jobs which require panel lengths in excess of shipping limitations (45 feet to 65 feet, depending on location), Garland recommends full length panels (no end laps or splices) formed on site by full size factory-type equipment, and operated by a full-time experienced technician.

.6 Mechanically Curved Panels: Panels shall be mechanically curved to the exact radius of each curved roof area. Panels may be mechanically curved in the factory or on site. Mechanical curving equipment shall be operated by a full time experienced technician. Flat panels conformed to the roof shape are not acceptable and will be rejected.

.7 Tapered Panels: Tapered panels shall be formed from a single piece of metal. Tapered panels formed from multiple pieces of joined metal are unacceptable. All performance tests must be applicable for the greatest panel width of the tapered panels. Tapered panels must be designed to accommodate thermal expansion and contraction while fixed at the narrowest end of the panel.
