SUNTUF® BEEHIVE
HIGH IMPACT ROOFING

All Palram polycarbonate products can be cold bent onsite during installation, subject to a minimum radius. The radius varies based on the chosen product. For flat sheets such as PALSUN & SUNLITE, the rule-of-thumb for the minimum radius is the thickness multiplied by 200. Please check the Palram catalog for more detailed specifications.

The minimum allowed bending radius of the polycarbonate is 200 times the thickness of the sheet, for example, a 2 mm sheet has a minimum 400 mm bending radius.

Corrugated polycarbonate sheets are installed as a homogeneous part of the metal roof. For more information, please review Palram’s installation instructions for the desired profile.

Pre-drilling the holes ensures that the panels have room to expand and contract properly with temperature changes. Skipping this step can lead to distorted, warped or cracked panels.

Polycarbonate sheets block UV radiation by absorbing it. This absorption mechanism can cause degradation to the material, and to prevent this from happening, the sheet is coated with a special material.

For this reason, it is recommended that the sheets are installed with the marked UV protective layer facing outward. Moreover, most of the sheets are only protected on the side that is clearly marked as such.

Palram offers various LT% parameters – from 0% to 90%. In addition, we offer a color called a “diffuser” that allows 85% of the light in while diffusing it by 100%. The result is a light-transmitting panel that is not transparent but is highly translucent.

Yes. Corrugated sheets can be cold-curved to create arched shapes. It’s important to follow the relevant Palram specifications for minimum radius in cold-curving, which can be found in the Installation Instructions of the relevant sheets. In addition, corrugated sheets should be arched so that the corrugations themselves are curved lengthwise.

PALRAM’s polycarbonate products are shielded with a UV protection layer that guards against photodegradation, yellowing, and brittleness. This protects the sheets from the harmful impact of UV radiation and helps to maintain light transmittance and quality for many years. Our products come with a 10-year warranty against loss of light transmittance. Upon special request, we can provide an enforced UV protection layer with a longer warranty.

Yes, Palram’s MetalMatch technology enables us to create a covering that will fit any existing structure without requiring any additions.

Palram created specific loading tables for each product. Please visit our website and download the specific catalog.

• Never use abrasive or high alkaline cleaners on any Palram polycarbonate products.
• Do not leave cleaners on Palram polycarbonate for extended periods of time. Rinse immediately with cold, clean water.
• Do not apply cleaners in direct sunlight.
• Never use sharp objects, squeegees or razors on polycarbonate.
• Do not clean with gasoline.
• Always practice safety first and never step directly on a polycarbonate panel.
• Always test cleaners in a small inconspicuous area prior to cleaning the entire panel to ensure against adverse results.
• Avoid allowing the pressure washer spray tip to come too close to the panel. Pressure washers often have enough pressure at the spray tip to penetrate or tear the panel.
• Avoid dry cleaning as sand and dust particles clinging to the exterior of the panels may scratch the surface.

This decision depends on the application – some of the colors are transparent and some are translucent. If a see-through material is needed, then haze should be smaller than 1% and the LT% should be based on the illumination design. If a translucent effect is needed, then the haze should be 100% and the LT% based on the chosen color.
