What goes into it
Every quotation lists this, so you can compare like for like. How prices are worked out →
| Part | LINEA standard | Why it matters |
|---|---|---|
| Sheet steel | 1.6 mm (16 g) TATA Galvano, 120 GSM zinc | Gauge gives stiffness; zinc protects against rust. |
| Frame & mullions | Laser-cut, CNC-folded, tab-located | Square corners and straight frames that fit the opening. |
| Shutter frame | 40 × 20 × 1.6 GI tube | Rigid shutters that don't sag over the years. |
| Grill | ¾" GI square tube @ 100 mm | Security bars through the frame; round bar on request. |
| Hardware | SS hinges, handles, tower bolts | No rust stains at the hinges. |
| Fixing | Hold-fasts welded, grouted in | Frame locked into the masonry. |
| Finish | Zinc-rich at every weld + epoxy primer | Welds are where rust starts — each one is treated. |

Good to know
Will GI steel windows rust in Kerala's monsoon?
We use TATA Galvano sheet with a 120 GSM zinc coating, repair every weld with zinc-rich coating and finish with epoxy primer. Keep the windows painted (your painter applies the top coat) and they stay protected. For coastal sites ask for heavier Z275 zinc — we quote both.
Are glass and paint included?
Our standard price covers the steel window with grill, hinges, handles and epoxy primer, ready for your painter. Glass is fitted by your glazier unless you ask us to include it — either way the quotation states it clearly, line by line.
Can you make any size or design?
Yes. Each window is designed from your plan sizes in our studio — any number of panels, top lights, kitchen windows, French windows, ventilators, arch tops. You see the drawing before we cut.
Is GST included in your price?
Every quotation shows the price before GST, the GST and the total separately, and you get a GST tax invoice from LINEA Steel Fabricators LLP.
