  • How do you install a 90 deg corner?
  • Installing these RoofArt steel gutter corners is very simple as they come with the joint brackets already built in.  Once gutters are cut and positioned in the desired locations, the gutter corner simply clips in and clamps down tightly ensure a firm fitting.

  • Are internal and external corners the same?
  • No, it is important that you order the correct type of corner.  The rolled front edge of the gutter means that external and internal gutter corners are not interchangeable.
  • Can RoofArt gutter corners be used with other makes of steel gutter?
  • The only make of gutter that we are aware of RoofArt being compatible with is Lindab Rainline.  Other steel rainwater systems by Zambelli, Alumasc, Infinity, Galeco etc are manufactured to a different shape and so will not line up with the RoofArt system.
  • Can I cut RoofArt gutter corners?
  • Cutting the gutter corners to make shorter legs can be done although you would need to ensure the whole bracket section is cut off and then a new joint bracket is used to fix the corner back to a gutter run.  We would always recommend cutting the adjoining gutters rather than cutting the steel gutter corner.
