Use ink pen, chalk line or coloured pencil for marking cladding sheets prior to cutting.  Do not use lead pencil for marking Zincalume®, Type AZ or Type AM - coated and pre-painted steel.  Cut by shear only, using nibblers or hand snips.  Remove all cutting and drilling debris.

3.19
FIX SHEETS

Fix sheets in place using the fastening system required by Taranaki Steelformers for specified profiles, making due allowance for dynamic local wind pressures on the building and thermal movement in the sheet.

3.20
INSTALL FLASHINGS

Flash to parapets, roofs and penetrations to detail.  Flashings to be installed on timber framing with a moisture content of less than 18%.  Where no detail is provided flash to NZMRM CoP recommendations and Taranaki Steelformers and NZBC E2/AS1 requirements.  Cut accurately and fix using sealant and rivets to detail and to Taranaki Steelformers requirements to form a weatherproof cover.  For visible flashings, plan joints/junction to take account of the aesthetic requirements.

3.21
FLASHING PENETRATIONS

Flash all penetrations through the cladding.  Fit pipe flashings with a proprietary collar flashing, with other penetrations flashed as detailed and to provide a weathertight installation.  Ensure that flashings are set to avoid any ponding of water.

3.22
USE OF SEALANTS

Select and use sealants only as recommended by Taranaki Steelformers.  Apply sealant in two narrow beads transversely across flashing intersections, close to the two edges.  Avoid exposing sealant on outside surfaces.

completion
3.23
COMPLETION MATTERS

Refer to 1270 CONSTRUCTION for completion requirements and if required commissioning requirements.

Use this standard generic clause and if appropriate add additional special requirements.

3.24
COMPLETE

Ensure the work is complete with all flashings, finishing and trim properly installed so the cladding system is completely weathertight.

3.25
MAINTENANCE

Reference must be made to selected material suppliers literature for exact details of maintenance requirements. Maintenance and regular inspection schedules will be specified as a condition of the warranty.

 

Minimum recommended maintenance in addition to rain washing is manual washing every 3, 6 or 12 months depending on environment category, more often for areas without adequate rain washing.

ISO Category 5 (very severe environment) maintenance every 3 months, ISO Category 4 (severe marine environment) maintenance every 6 months, ISO Category 3 & 2 (marine/moderate environment) maintenance every 12 months (Zincalume® and Galvsteel® every 6 months).

Pan width:

Standard pan widths are 250mm, 330mm, and 470mm (between vertical battens). Custom pan widths are possible.  It is standard Steelformers practice that the pans are run with swages, for extra rigidity and strength, and for reducing wind-driven roof noise. If the customer wants a smooth finish to the pans it is at Steelformers discretion.  In very high and extra-high wind zones pans must be run with swages.  Quattro Steelformers TCS Cladding is not suitable for use in Specific Engineering Design (SED) wind zones.

Pan fixing:

No clips used for this cladding.

Vertical batten size:

Steelformers recommend 45mm x 45mm H3.1 dressed timber battens (not supplied by Steelformers).

Note - Vertical battens are fixed by the cladding Installer/Applicator, as they install the cavity batten, to suit pan width.

 

Steelformers recommends nog spacing at 450mm centres in all wind zones, (co-ordinate with timber framing section) behind cladding

If the customer wants a smooth finish to the pans it is at Steelformers discretion.  In very high and extra-high wind zones pans must be run with swages.  45mm Snapseam Cladding is not suitable for use in Specific Engineering Design (SED) wind zones.

Pan fixing:

Concealed clips fixed to Steelformers technical information. Refer to various fixings listed in table below. Refer to NZMRM Code of Practice or consult with Steelformers representative, to confirm Fixing Clip spacings and fixings, to suit Wind Zone and framing type, respectively.  In all wind zones it is Steelformers standard practice that the clips are fixed to all nog/girt lines for wall applications.

Substrate:

None (to be installed over a drained cavity for all walls internally lined.  Can be installed direct fixed for unlined walls) or

Substrate:

minimum 12mm pywood H3.2 CCA, Stress Grade F11, CD Face Grade

The specifier may prefers a plywood substrate e.g. for improved noise attenuation to MRM recommendations.  The minimum requirement for a substrate is a plywood sheet 12mm thick, H3.2 CCA treated (water based system), stress Grade F11, CD Face Grade, installed moisture content 18% or less. Substrate fixed to structural frame to NZBC, and Taranaki Steelformers technical information.

 

Steelformers recommends nog spacing at 450mm centres in all wind zones, (co-ordinate with timber framing section) behind cladding
