GI Square Hollow Pipe Manufacturers in India play a pivotal role in supplying high-quality steel solutions that meet the demanding requirements of multiple industries. Renny Strips, a trusted name in the sector, offers a wide range of GI Pipes and Tubes that combine strength, durability, and resistance to environmental challenges. These products are engineered using the Hot Dip Galvanizing process, providing a minimum 385 GSM zinc coating, which ensures superior corrosion protection and longevity.
What Is GI Square Hollow Pipe?
GI square hollow pipe is a square-section steel tube coated with a layer of zinc through hot-dip galvanizing (GI stands for "galvanized iron," though the base material is steel). The galvanizing process protects the underlying steel from rust and corrosion by forming a protective zinc barrier, while the square hollow cross-section provides even load distribution and efficient use of material for structural applications. GSM (grams per square meter) refers to the weight of zinc coating applied per unit area — a higher GSM generally means a thicker, more durable protective layer.

Durability and Strength for Industrial Applications
The industrial sector demands materials that can withstand heavy loads, harsh environments, and continuous usage. Renny Strips GI Square Hollow Pipes are available in sizes ranging from 25×25 mm to 100×100 mm with thicknesses from 1.4 mm to 5.5 mm. This extensive range allows industries to select the ideal pipe for applications such as scaffolding, structural frameworks, and construction support. The square hollow design ensures even load distribution, making these pipes a reliable choice for structural projects.
Engineered with strict adherence to industry standards, these pipes exhibit excellent tensile strength, making them suitable for both vertical and horizontal load-bearing applications. The galvanization process not only protects the steel from rust and corrosion but also enhances its fire resistance. For industries operating in coastal or humid regions, these features are particularly crucial as they ensure a longer service life even in challenging conditions.
Corrosion Resistance and Environmental Protection
Corrosion is a major concern for industrial materials, especially in environments exposed to moisture, chemicals, or extreme weather conditions. Renny Strips addresses this challenge with Hot Dip Galvanized pipes that provide a robust zinc layer, acting as a protective barrier against rust and environmental degradation. This makes GI Square Hollow Pipes an ideal choice for coastal areas, chemical plants, and outdoor construction projects.
Additionally, the pipes offer termite protection, which is a unique advantage in regions where wooden scaffolding or frameworks may be susceptible to damage. The combination of corrosion and termite resistance ensures minimal maintenance costs and extends the lifespan of the installations. Industries can invest in these pipes knowing they provide long-term reliability and safety.

Frequently Asked Questions
What is GI square hollow pipe used for?
GI square hollow pipe is used in scaffolding, structural frameworks, construction support, industrial fabrication, agricultural infrastructure (greenhouses, irrigation, fencing), transportation, and energy and utility applications such as pipelines and cable protection.
What sizes and thicknesses are available?
Renny Strips manufactures GI square hollow pipe in sizes from 25×25 mm to 100×100 mm, with thicknesses ranging from 1.4 mm to 5.5 mm, and offers custom sizing on request.
What does GSM mean in galvanized pipe coating?
GSM stands for grams per square meter, referring to the weight of zinc coating applied to the pipe. A higher GSM rating indicates a thicker zinc layer, which generally means better corrosion protection and a longer service life. Renny Strips pipes carry a minimum 385 GSM coating.
What's the difference between GI pipe and MS pipe?
GI (galvanized) pipe has a zinc coating applied through hot-dip galvanizing for corrosion resistance, while MS (mild steel) pipe typically has no such coating and is more suited to applications where corrosion exposure is limited or where a coating will be applied separately.
Does GI square hollow pipe offer termite protection?
Yes. The galvanized coating on these pipes provides termite protection alongside corrosion resistance, which is a particular advantage over wooden scaffolding or frameworks in regions prone to termite damage.
