Product Description
Galvanized Square Steel Pipe Refers to a kind of steel pipe used to protect the line after the surface of the steel pipe is galvanized by a special process.
Galvanized steel should be used anywhere rust protection is required or desired to create durable, long lasting products and structures. The quick fix options to prevent rust, like that of painting or coatings of grease and oil, tend to be unreliable and only provide short-term corrosion protection requiring continued maintenance.
Galvanized materials require less maintenance, less repair costs, have a longer life expectancy than that of uncoated steel, and have a lower initial cost than other coating options.
Features
Semi-smooth, zinc finish
Great corrosion resistance and ideal for outdoor use or exposed environments.
Galvanized square tube is available in sizes ranging from 5/8” x 5/8” x 16ga up to 4” x 4” x .250.
Galvanized rectangle tube is available in sizes ranging from 1” x 2” up to 2” x 3”.
Sold in full lengths only, 24’ in length.

Product Application
1. Construction engineering: Galvanized steel pipes are often used in indoor and outdoor piping systems, such as HVAC systems, tap water pipes, fire-fighting pipes, etc.They can prevent pipes from being corroded and rusted, and improve the life and durability of pipes.
2. Road traffic facilities: Galvanized steel pipes are also widely used in street light poles, bridge guardrails, signal poles and highway guardrails.These facilities need to have strong corrosion resistance and durability to ensure the safety and stability of highway operation.
3. Agriculture and horticulture: Galvanized steel pipes can also be used for agricultural and horticultural purposes such as brackets for agricultural locomotives, fruit tree brackets, fences, and scaffolding.These application scenarios require more corrosion-resistant and durable materials.
4. Other fields: Galvanized steel pipes can also be used in nuclear power plants, offshore drilling platforms, ships and other fields.The production equipment and engineering of these industries need to have high anti-corrosion, anti-rust and durable properties.
