Solid Sheets
- Roll products must be stored horizontally. Storing roll products in vertical position may cause fine cracks on cutting surfaces.
- When you have to store a roll product in vertical position, store it in such a way that the cutting surface can be protected.
- Direct contact with a cement floor or a papered floor may cause cracks.
- Do not have roll products dropped from the vehicle when you unload them. Fine cracks may occur on cutting surfaces by impact.
- Do not move roll products in vertical position. Cracks may occur on the sides.
- Must avoid storing the products along with a chemical agent (organic agent such as thinner, gasoline, lamp oil, or anti-rust oil) in a storehouse or a room. Doing so may cause damage on the products.
- Store the products indoor at a room temperature (23 ℃, humidity: 50% or less) when you need to store them for a long period.
- Do not store or expose the products to direct sunlight for a long time.
- Doing so may cause difficulty in removing the protective film, deformation to the products in the summer season, and/or cracks in the winter season.
- When using a silicon sealant, select an alcohol type. Using an acetic silicon sealant or an oxide silicon sealant may cause surface corrosion and/or solvent cracks on the product.
- Sufficient drying and ventilation is required when you use a silicon sealant.
- When you need to use a bolt (or a screw), do not select one with oblique threads.
- A bolt or a screw with oblique threads may cause cracks on the product.
- Cut a hole on the product at a distance - which is more than twice the diameter of the drill – from the edge.
- d = 2 × Diameter of drill (Diameter of drill: 6mm or greater)
- Install the product in consideration of the linear expansion coefficient:When the difference in temperature is 50℃, the expansion length of the product with the PC length of 4m is 14.0mm approximately.
- 7 mm/mm/℃×10-5(Linear Expansion Coefficient of PC) × 4000 mm (Length) × 50℃ (Difference in temp.) = 14.0mm
- Cut a hole of which the diameter is 2 - 4mm greater than that of the bolt (or screw), and then tighten the bolt (or screw) with an appropriate accessory such as a washer.
- Do not tight the blot directly when you join the product with the support (chassis). Cracks may occur.
- When you install the product in curvature, make the radius of curvature (R) greater than 180 times of the thickness.
- When the radius of curvature is less than that, cracks may occur on the product due to tensional stress.
- Radius of Curvature (R) > 180 × Thickness of Product
- When you use cement or paint, install the product after sufficient cleaning and ventilation.
- Contact with paint or thinner on the product surface may cause deformation and/or cracks.
- Direct contact with cement on the product surface may cause cracks.
- When you use a roll product, install it in the rolled direction.
- Installing the roll product in the opposite direction may cause Cracks
- Do not have a welding rod or sludge contact with the product directly.
- Doing so may cause damage on the product.
