33.7mm Tube Clamps FAQs

What type of projects are 33.7mm tube clamps suited for?

33.7mm tube clamps are a popular choice for medium-duty frameworks where a combination of strength, ease of handling, and versatility is needed. They are widely used for public handrails, mezzanine safety barriers, light industrial guardrails, and pedestrian walkways. The 33.7mm diameter is also preferred in settings where the structure must comply with accessibility guidelines, such as providing a comfortable hand grip for all users.

Will these clamps fit exactly 33.7mm tube?

Yes. These fittings are specifically engineered to fit tube with a 33.7mm outside diameter, ensuring a precise and secure connection. Using the correct tube size is critical for maintaining structural integrity, preventing movement, and ensuring compliance with safety regulations. Tube that is undersized or oversized can result in poor fitment and reduced load capacity.

Can these fittings be used outdoors?

Yes. The hot-dip galvanised finish to EN ISO 1461 creates a robust zinc coating that protects the steel from corrosion. This makes 33.7mm tube clamps suitable for year-round use in exposed environments such as coastal locations, industrial yards, or public spaces. For installations in highly corrosive environments — for example, chemical plants or marine areas — additional protective coatings or stainless steel fittings may be recommended.

Are they compliant with UK safety regulations?

When used with compatible tube and installed correctly, 33.7mm tube clamps can be part of a system that meets British Standards for handrails and guardrails. Compliance depends on more than the fitting alone — factors such as post spacing, anchoring method, and load capacity must also meet the requirements of the Work at Height Regulations and relevant building codes. Always consult a competent person or engineer for safety-critical applications.

Can the system be modified after installation?

Yes. One of the key benefits of a modular tube clamp system is the ability to adapt the layout without permanent alterations. Sections can be dismantled, repositioned, or extended by loosening the grub screws with an Allen key. This makes the system cost-effective for evolving site layouts or temporary works where relocation is required.

Do you offer bulk order discounts?

Yes. BM Steel supplies trade customers and large-scale contractors, offering competitive pricing on bulk quantities of 33.7mm tube clamps. Discounts are typically tailored based on volume, frequency of orders, and whether other BM Steel products are included in the same order.
