We use 100mm heavy-duty hollow sections that are grouted directly into concrete for stability, ensuring your terrace cabin or pergola remains solid through Delhi’s harsh weather and monsoon winds. ### Structural Integrity We prioritize load-bearing capacity in every build. For terrace extensions and cabins, our framework utilizes heavy-duty Mild Steel (MS) sections. By using 100mm columns and rafters, we ensure the structure can support polycarbonate roofing or louvers without bowing or instability. ### Corrosion Protection Outdoor environments in the NCR region require specific attention to rust prevention. Our process includes a mandatory anti-rust red oxide primer application on all steel components. This is followed by a finish layer of automotive-grade PU paint in Matte Black or Dark Grey, providing a durable barrier against humidity and seasonal rain. ### Assembly & Installation We handle the entire fabrication process on-site or in pre-fabricated sections. * **Grouting:** Pillars are grouted into the concrete slab to provide structural anchoring. * **Roofing:** Polycarbonate sheets are installed with specific overlap techniques to prevent water leakage during monsoon. * **Surface Finish:** Our welding joints are cleaned and smoothed to maintain a clean, modern aesthetic that fits into contemporary home or commercial designs. This systematic approach allows us to deliver consistent results for complex terrace modifications and independent outdoor structures. ## About Green Cap Landscape At Green Cap Landscape Services, we focus on the construction work that makes a space functional. We handle the heavy steel fabrication and structural framing ourselves, ensuring your terrace or garden addition is built to last.
