The following is a detailed introduction about galvanized square tube：

Material characteristics

Strong corrosion resistance：The galvanized layer can effectively prevent air and moisture from coming into contact with the surface of the steel pipe，Thereby preventing the occurrence of oxidation reactions，Extended service life。

Good antioxidant properties：Even in harsh environments，Can also maintain good condition for a long time。

High mechanic strength：Made from high-quality steel materials，Capable of withstanding significant tensile and compressive forces，Simultaneously effectively resist collisions and impacts。

Beautiful and generous：The galvanized layer is uniform and shiny，Improved overall aesthetics。

Easy to maintain：Compared to other metal materials，The maintenance cost of galvanized square tube is lower。

Production process

Galvanized square tubes are mainly divided into hot-dip galvanized square tubes and cold-dip galvanized square tubes，Each production process has its own characteristics：

Hot dip galvanized square tube：Immerse the square tube into boiling zinc solution，Zinc reacts with the surface of steel pipes，Form a sturdy protective film。This galvanizing method ensures uniform coating thickness、Strong adhesion，Has superior anti-corrosion performance。

Cold galvanized square tube：Using electrochemical principles to form a zinc layer on the surface of square tubes，Realize anti-corrosion function。Cold dip galvanized coatings mainly use electrochemical principles for corrosion prevention，Therefore, it is necessary to ensure sufficient contact between zinc powder and steel，Generate electrode potential difference。

Specification

Common side length specifications：follow10mm×10mmarrive300mm×300mmunequal，Common ones include20mm×20mm、30mm×30mm、40mm×40mm、50mm×50mm、60mm×60mm、80mm×80mm、100mm×100mmclass。

Wall thickness specification：Usually from1.0mmarrive5.0mmunequal，of which1.2mmand1.5mmThe specification of galvanized square tube with thickness is more common。

length specification：Common lengths include3m、4m、6mclass，Specific lengths can also be customized according to specific engineering requirements。

Weight calculation formula：The weight calculation formula for each meter of square tube is4×thickness×（Side length－thickness）×0.00785，The side length and wall thickness are both measured in millimeters（mm）In units。

application area

Galvanized square tube due to its excellent performance，Widely used in the following fields：

Construction field：Used for building structural frameworks、Steel structure platform、stair railing、handrail、guardrail、Building curtain walls, etc。

Machinery manufacturing：Used to make support structures for various mechanical equipment，Like a conveyor belt bracket、Working platform、Bicycle frame、Automotive components, etc。

power industry：Used for transmission towers、Transmission line brackets, etc。

communication devices：Used for telecommunications towers、Antenna bracket, etc。

agriculture：Used for building greenhouses、Livestock sheds, etc。

maintenance

Avoid direct sunlight：Long term exposure to sunlight can cause fading or damage to the galvanized layer，Affects its anti-corrosion performance。

regular inspection：Check if the galvanized layer is complete，If there is any damage, it should be repaired in a timely manner。
