Steel Window Frames | Sizes and Prices
NJR Steel branches stock a broad range of steel window sections. These sections are used to manufacture window frames for domestic, commercial and industrial buildings alike. Unparalleled in strength, steel window frames are thinner than their aluminium and tier counterparts, giving them the ability to hold larger glass panels and thus display a greater outside view.
