A small additional investment for a heavier grade garage door.

Shadowing or oil canning can be defined as a perceived waviness in the flat areas of metal panels. Oil canning is an inherent part of light gauge cold-formed metal products, particularly those with broad flat areas such as garage doors. Most manufacturers warn against shadowing or obvious oil canning and will not cover in warranty provisions. By using G300 steel, which is a stronger grade of steel than traditional steel used for garage doors, minimises visual oil canning.

A great range of designs and colours to choose from at an affordable price.
