Why Frame Material Matters for Long-Lasting Window Grills in Mumbai

Mumbai’s humid climate and monsoon rains demand careful selection of window grill frames. At Mewelder, we’ve seen how poor material choices lead to rust, corrosion, and weak grills. Here’s a breakdown of frame materials and why 20x5 mm steel patti is the ultimate solution for Mumbai homes.

Common Frame Materials – Pros & Cons

1. Angle Frames (L-Shaped Steel)

• Problem:

  • Water accumulates in the inner corners, causing rust and corrosion during monsoons.

  • Weakens joints, leading to grill collapse over time.

• Why Avoid?

  • Common in low-cost grills but unsuitable for Mumbai’s humidity.

2. Rod Frames (Round or Square Rods)

• Problem:

  • Rods bend easily under weight or pressure, especially in wide grills.

  • Poor load distribution causes sagging and misalignment.

• Why Avoid?

  • Risky for balconies or large windows in high-rises.
