The Square Tube Base Flange is a high-strength anchoring solution designed to securely fix 50.8mm x 50.8mm square stainless steel posts to floors, walls, or staircases. This precision-engineered base flange features a 100mm x 100mm flat mounting plate with four pre-drilled holes for stable attachment to concrete, wood, or steel substrates using bolts or screws. The 30mm collar height provides a deep, rigid socket that stabilizes the tubing, ensuring the structural integrity of the entire railing framework. Manufactured from premium AISI 304 or 316 stainless steel, these square handrail fittings offer exceptional resistance to rust and environmental corrosion, providing a clean, professional finish for both residential and commercial architectural projects.

Q1. What are the specific dimensions of this Square Tube Base Flange?
A: This flange is designed for standard 50.8mm x 50.8mm square tubing. The base plate (Dimension A) measures 100mm x 100mm, and the vertical collar (Dimension B) has a height of 30mm to provide robust support for the inserted post.
Q2. Which material grade is best for an outdoor or coastal installation?
A: For maximum durability in outdoor or high-moisture environments, AISI 316 stainless steel is recommended due to its superior chloride resistance. AISI 304 is a cost-effective and durable choice for interior applications in dry, controlled environments.
Q3. Does the installation of this flange require welding?
A: No. This base flange is designed for weld-free assembly. The tubing is inserted into the 30mm collar and typically secured using high-strength structural adhesives or internal mechanical fasteners, maintaining the sleek aesthetic of the stainless steel.
Q4. How is the flange secured to the floor or mounting surface?
A: The base plate features four pre-drilled holes in the corners. It should be mounted using fasteners appropriate for the substrate, such as wedge anchors for concrete or heavy-duty lag bolts for timber surfaces.
Q5. How do I maintain the finish of the flange?
A: Regular maintenance is essential to prevent "tea staining" or surface oxidation, even on high-grade steel. We recommend cleaning with a mild, pH-neutral detergent and water, always wiping in the direction of the metal grain. Avoid abrasive pads or carbon steel brushes, as they can damage the protective oxide layer.
Q6. Can this flange be used for wall-mounted applications?
A: Yes. While commonly used as a floor mount for vertical posts, the flat base plate allows it to be used as a heavy-duty wall flange for horizontal framework terminations or support brackets.
