28.2 The chief advantages of plywood over a single board of the same thickness is the more uniform

strength of the plywood, along the length and width of the plywood and greater resistance to

cracking and splitting with change in moisture content.

of heating may be anything from 2 to 60 minutes depending upon thickness

28.4 When water glue is used, the wood absorbs so much water that the finished plywood must be dried

carefully. When synthetic resins are used as adhesive finished plywood must be exposed to an

atmosphere of controlled humidity until the proper amount of moisture has been absorbed.

WWR and CWR depending upon the adhesives used for bonding and veneers, and it will be further

classified into six types namely AA, AC, AC, BB, BC and CC based on the quality of the two faces,

in proper sequence without damaging either the concrete or the forms to be removed.

The props of centering shall be provided on firm foundation of base of sufficient strength to carry

the loads without settlement.

The centering and form work will be inspected and approved by the Engineer-in-charge before

Chemical Resistance:

The Polycarbonate sheet should be excellent resistance to most chemicals, resistance to specific

compounds depends on concentration and temperature, duration of exposure and stress within the

sheet. Contact with plastic coated metal sheets, wet wood preservatives, solvents and alkali cleaners

should be avoided.

Impact Resistance:

The Polycarbonate sheet should be highly resistant to breakage due to impact. Simulated hail tests have

shown that 20mm diameter hailstones impacting the sheet at a speed of 21m/s will not cause breakage.

Cutting and drilling Cutting –

Polygal multiwall sheets can be cut easily and accurately with standard woodworking equipment. This

includes standard circular, jig, or table saw with a circular blade having 8-12 teeth per inch (fine toothed

blade). Saw dust should be blown out (or) vacuumed out of the flutes. If using compressed air, insure that

there is a moisture separator on the compressor to insure moisture is not introduced into the flutes.

Thinner gauges can be cut with a box knife. It is important that the knife is sharp. Drilling - Holes can be

drilled by a power drill using standard high speed steel twist drills or drills with an angular wedged bid.

When drilling, support should be given immediately beneath the drill to avoid vibration. Very clean holes

are easily obtained. The use of liquid cooling media is not recommended. Trimming – standard box cutting

Planning the Supporting Structure

• Install the sheets with the ribs parallel to rain flow and with a slope of at least 10º (1:12 pitch). In wall

and gable applications… always ensure that the ribs are positioned vertically. • Supporting beams must

be at least 30 mm (1.2”) wide to ensure good anchorage of sheets and fastening accessories. • In case of

arched structure, check the smallest permissible cold bending radius (R) according to the sheets

thickness. • Ensure that a qualified professional checks and approves the structure before execution.

Preparing the Supporting Structure

• Complete all the metalwork and painting before beginning sheet installation work. • Check the

dimensions on site, and plan the roofing requirements before ordering Polygal products for the project.

Preparing the Sheets

• Remove the grey protective film. • Fold back the printed sheet protection film 4” (inches) on each side.

• Attach Perforated Edge Tape to the upper and lower edges of the sheet.

Preparing the Edge Profiles

Signature of Bidder Executive Engineer, GIDC, Surat

• Use an Aluminum or Polycarbonate Edge Profiles to protect the lower edge of the sheets. For the upper

edge’s protection also a Polycarbonate Edge Profiles can be used. • Use a metal saw to cut the Aluminum

Edge Profiles into pieces matching the width of sheets to which they will be attached. • Drill drainage

channels to allow for the flow of condensed water along the profiles used for the bottom section of the

building’s roof. Drill holes 6”- 12” apart using a 5/16” drill bit. • Attach the edge profile to the sheet with

the short side on top of the sheet.

Sheets Installation

Step 1- Place the sheets with the side protected by the printed film upwards.

Step 2- Slide the base connecting profile underneath the sheet flank and use self drilling screws to

anchor them to the structure.

Step 3- Position the connecting profile cap in place. For a Polycarbonate Connection Profiles with a

shock-absorbing support under the sheet, use a rubber mallet to connect it to the base. For Aluminum

Glazing Systems, anchor the Cap Profile to the Base Profile with applicable screws (see Polygal

Accessories Catalog).

Step 4- Continue to add sheets, and profiles until reaching the end of the building. After completing

installation, remove all the protective film from the sheets as soon as possible.

Finish and Fixing Reinforcements

• Place fixing screws with fixing gaskets only in the support frame lines. • Do not over-tighten screws. For

best results always use Polygal screws and accessories, designed specifically for use with Polygal sheets.

Mode of Measurements:

The rates shall be included all materials and labor and it is measured on the basis of sqmt.
