Advantages of Steel
1. The width of the outer and the inner frames so necessary in the wooden windows is reduced for steel windows to the extent of about 25% without reducing the area for light and ventilation.
2. For a predetermined glazed area the size of the opening can be reduced for steel windows, reducing thereby the cost of lintels and sills.
3. Steel casements are proof against attacks by white-ants & natural calamities.
4. Steel casements are free from hazards of fire.
5. Steel casements afford greater facilities for having different types of openable parts.
6. They are immune from weather effects and therefore are not subject to expansion and contraction as in the case of wooden windows, doors or sashes.
7. They are superior to their wooden counterparts in elegant show and streamlined finishing.
8. They have more durability and precision in manufacture.
9. The cost of maintenance is next to nothing with a very, very long life.
10. In the final analysis the cost of steel casement will be found less than that of a wooden window, door or sashes.
