What is the Square Hollow Roll Forming?
A square Hollow Roll Forming is a structural element with a hollow core inside, designed in square or rectangular shapes to cater to the needs of consumers. Square Hollow Roll Forming is a product of the hollow roll forming machine produced in standard sizes, including equal length and width ranging from 100×100 millimeters to 150×150 millimeters, with typical thicknesses between 0.2 and 0.35 millimeters. The variety of sizes available allows investors and construction contractors to easily choose square steel sections for different projects.
In addition to Square Hollow Roll Forming, there are also rectangular Square Hollow Roll Forming known for their robust structure, excellent load-bearing capacity, and high durability. They are widely used in construction and the fabrication of beams, steel frames, pipes, staircase railings, with varying dimensions, typically ranging from 100-150mm in width and length and 0.2-0.35mm in thickness.
There are some different materials used for Hollow Roll Forming:
Aluminum: While this type is expensive, it has the advantage of being lightweight, easily roll-formed, and durable in natural environments. However, it has lower load-bearing capacity, so it is less commonly used.
Tin and Zinc-Coated: These materials are highly durable and exhibit good ductility but come at a higher cost.
Steel: Steel Square Hollow Roll Forming are typically made from medium-quality carbon steel with a tensile strength of around 400 mpa. However, they are less durable in atmospheric conditions and susceptible to oxidation. To address this issue, zinc coating or electrostatic painting is often applied to the coil blanks to protect the inner steel and limit the formation of rust without requiring an additional protective paint layer.
Advantages of Square Hollow Roll Forming
With its high applicability in various construction and life sectors today, Square Hollow Roll Forming are the top choice for many consumers. This has led to an increasing number of investors in hollow roll forming machines due to their trust in these sections, their versatile applications in all fields, competitive prices, and long lifespan.
Cost-Effective: Square hollow roll forming (including rectangular roll forming) are cost-effective products as they are manufactured from readily available materials. This affordability makes them a popular choice among consumers. However, zinc-coated steel products will have a slightly higher price due to their superior rust and corrosion resistance in moist or acidic environmental conditions.
Long Lifespan: Square hollow roll forming products have a long service life due to their high durability and excellent load-bearing capacity. The average lifespan of steel box sections can reach up to 15 years, depending on weather conditions and usage. Especially, galvanized steel box sections can extend their service life to over 30 years in standard conditions and over 25 years when exposed to corrosive substances, such as in industrial areas or coastal regions.
Easy Inspection and Repair: After a period of use, consumers can easily inspect the welds and joints on the steel sections with the naked eye. If issues are identified, they can contact repairmen or seek advice from engineers. However, with their exceptional durability and quality when applied in various projects, particularly galvanized steel box sections with their extended lifespan, they save consumers time and money in maintenance and repairs.
Hollow Roll Forming Machine – Square Hollow Section Manufacturing Machine
