Welding cross flush angle

The Strofix welding cross flush angle is an AISI 304 stainless-steel perpendicular tube junction for Ø42.4 × 2 mm or Ø48.3 × 2 mm railing tubes. The fitting creates a smooth, flush-profile cross connection where one tube passes over or through another at a perpendicular angle. The Ø42.4 variant has a 92 mm height; the Ø48.3 variant has a 98 mm height. Supplied in satin finish. Attached by welding (elements for welding included).

The welding cross flush angle is used where a handrail tube crosses over a post tube, or where two tubes intersect at a perpendicular angle in the railing system. The "flush" design ensures the external surface at the junction is smooth and continuous, with no visible clamp or bracket hardware. The fitting requires TIG or MIG welding for permanent attachment — this is a professional installation product for fabricators with stainless-steel welding capability. The two tube size options cover both the standard Ø42.4 mm and the Ø48.3 mm railing tube. AISI 304 stainless steel is suitable for standard interior and exterior installations.

The satin finish provides a uniform appearance. Post-weld finishing may be required to blend the weld zone with the surrounding satin surface.

Use cases:

• Handrail-over-post cross connections in railing systems
• Perpendicular tube intersections in balustrade frameworks
• Railing corner junctions where two tubes cross at 90°
• Professional railing fabrication requiring welded flush-profile cross joints
• Commercial and residential railing systems using Ø42.4 or Ø48.3 mm tubes

FAQ:

What tube sizes does this fitting fit?

Two tube sizes are available: Ø42.4 × 2 mm and Ø48.3 × 2 mm. Select the tube size in the dropdown at order time.

What is the fitting height for each tube size?

The Ø42.4 variant has a 92 mm height (H = 92 mm). The Ø48.3 variant has a 98 mm height (H = 98 mm).

How is this fitting attached?

The fitting is attached by welding. TIG or MIG welding is required for permanent attachment to the tubes. This product is intended for professional fabricators with stainless-steel welding equipment.

How does this differ from the adhesive-fixed cross flush angle?

A separate cross flush angle with adhesive fixing (elements for pasting) is available in the Strofix Elbows, Connectors category. The welded version provides a stronger, permanent joint suitable for structural applications. The adhesive version is suitable where welding is not possible or where a non-permanent joint is acceptable.

What does "cross flush angle" mean?

"Cross" refers to the perpendicular intersection of two tubes. "Flush" means the external profile at the junction is smooth and continuous. "Angle" refers to the 90° perpendicular crossing angle.

Is post-weld finishing required?

The weld zone may need grinding and polishing after welding to match the surrounding satin finish. The extent of post-weld finishing depends on the quality of the weld and the visual requirements of the installation.

About Elbows & Connectors

Elbows and connectors are stainless-steel joint fittings that link two sections of handrail or railing tube at a change of direction, creating a continuous, seamless-looking rail line around corners, up staircases and across straight joints. Flush elbows and angles slip over the tube ends and produce a smooth, weld-free joint on the visible surface; welding variants are permanently fused for a rigid connection.

Strofix supplies 15 elbow and connector products for Ø42.4 mm round pipe and 40×40 mm flat square tube, including fixed 90° flush angles, adjustable flush elbows (with one variant covering 0–70°), cross flush angles, tee ("T") connectors, tee corner connectors, inline fittings and welding flush angles — all in AISI 304 stainless steel with a satin finish, with AISI 316 and polished options on selected variants.

The correct fitting depends on tube profile, the angle of the direction change, the number of tube arms meeting at the joint and whether a screwable or welded connection is required.
