FAQ
Is the 30 x 30 x 2.5mm hollow section a good choice for structural support?
Yes, this section is manufactured from S235JR mild steel and meets BS EN 10219 standards, making it suitable for structural support in light to medium-duty applications. It's commonly used for framework, cross-bracing, and integrated assemblies in construction and fabrication.
What?s the correct surface preparation before applying protective coatings?
To ensure strong adhesion of paint or galvanising, the surface must be properly cleaned. This includes removing all mill scale, rust, and oil residues. Shot blasting or acid etching is recommended to maximise coating performance in outdoor or industrial environments.
Can I drill and tap fixings into this hollow steel section?
Yes, the 2.5mm wall thickness allows for clean drilling and tapping. For best accuracy, mark with a centre punch, and use sharp HSS drill bits. If threading, use appropriate cutting fluid and hand tools rated for mild steel.
How heavy is the 30 x 30 x 2.5mm steel hollow section per metre?
It weighs approximately 2.21 kilograms per metre. A full 7.5m length weighs around 16.6 kilograms?useful for planning installations, supports, or delivery.
Can I use this square section for visible or design-based applications?
Absolutely. The uniform shape and clean finish make it ideal for exposed architectural elements like railing frames, display fixtures, or structural accents. Just ensure the surface is finished or coated appropriately for the intended visual effect and durability.
How does this 30 x 30 x 2.5mm hollow section compare to circular or rectangular hollow sections?
Square Hollow Sections (SHS) provide uniform strength across both axes, making them ideal for balanced loads or symmetrical designs. Compared to Circular Hollow Sections (CHS), SHS offers easier connections and flat faces for welding. In contrast to Rectangular Hollow Sections (RHS), SHS provides a more compact profile, which can be beneficial in tight or decorative applications.
Is the 30 x 30 x 2.5mm hollow section compliant with UK building regulations?
Yes, when used as specified in structural plans, this section complies with UK regulations due to its BSEN10219 certification and S235JR steel grade. It is widely accepted for light structural and secondary support use across domestic, commercial, and agricultural settings.
