Note: Other specifications or requirements are subject to between Hoa Sen Group and customers .

Corrugated  forming:

-      Adjust the gap of rollers to fit in steel sheet thickness.

-      Rollers and forming rolls should be cleaned before corrugated forming.

-      Select steel sheet with an appropriate hardness and tensile strength when processing, especially in Klip Lock, Seam Lock, roof tiles, purlin or gutter roll forming.

-      Do not use lubricant for corrugated forming.

-      Should not roll steel sheet with too small radius because it can cause crack to the protective coating layers of the steel sheet .

Installation:

-      Wear soft-soled shoes when  moving on the roof in order to avoid scratching. Move softly on the steel sheet roof with the entire foot and on the location of screws with rafters and roof.

-      The fasteners used to fix cladding and accessory materials have the same or superior service life as the Hoa Sen product with which they are to be used. The rubber washer component of self-drilling screws must be manufactured from materials compatible with the roofing, walling and accessory material.

-      Use neutral Silicon sealant to have good adhesion.

-      Use natural pine oil or white shell oil and dry towels to clean the surface to apply adhesive.

-      The roof should be immediately cleaned to remove steel debris, rivets and other discarded steel objects after installation.

Apply the leading technology of pre-painting on zinc base, manufacture by the advanced technology production lines of Japan.
