Southern Steel Windows for Security

Southern Steel Windows can manufacture larger
complying sizes in steel joinery with minimal steel
frame, providing greater areas of glass, glazed doors
and other moveable glazed panels that require more
strength and stiffness. Our steel glazing systems are
finished with a caprithane wet paint system that can
be matched to any colour.
