1. The dimensions depicted above do not supersede the requirements of local construction codes. The distances depicted
above were calculated based on the structural properties with the following factors being taken into consideration: sheet
deflection, potential wind load, potential snow load, hail and application load according to usual construction practice.
2. When designing a new roof, it is strongly recommended that the slope be above 10% (5.7°). (Consult your local Palram
representative when recovering an existing greenhouse whose slope is shallower than this value).
3. The recommended maximum panel length is 7.0 m. The recommended maximum distance between the edge and first
purlin is 900 mm or the value dictated by the design engineer. (See drawing on page 4, Figure 8b).
Wall purlins distance can be increased by 10% of roof recommendation.
Calculate the number of sheets as follows:
1. Divide the length of the roof (the length of the gutter) by the effective width of the sheet.
2. Calculate the required length of the sheet (to be no greater than 7.0m) according to purlin to purlin distance, plus the
required extension beyond first and last purlin and overlap distance, if exists.
Handling and Storage
1. Palram corrugated sheets must be transported and stored horizontally on a flat, sturdy pallet whose dimensions are equal to
or larger than the sheets themselves. The sheets should be secured and fastened to the pallet. It is possible to store sheets
of smaller dimensions on top of larger sheets of the same type. (Never store sheets of larger dimensions on top of smaller
sheets!) SUNTUF Plus must be stored in a cool and shaded location.
2. Important: Never cover the pallet with, or place on the pallet, materials
that are good conductors of heat (e.g. Metal, pipes, clear or dark objects).
3. In cases where it is necessary to store the pallet outdoors, cover it with a
white opaque polyethylene sheet, card board, or any other material that
does not absorb or conduct heat. The total pallet must be covered.

Cutting
It is possible to cut SUNTUF Plus corrugated sheets using a circular saw with small teeth, rotating at a high speed, taking care
to advance the saw slowly. It is also possible to use a portable electric saw (Jig Saw) or sheet metal shears. In any case, it is
important to support the sheet in the vicinity of the cut and clean away the dust and debris generated by cutting.
