The Welded Base Plate (8 mm) is a critical structural component designed to securely anchor stainless steel handrail posts to flat mounting surfaces such as floors, decks, or walls. Specifically engineered for permanent welding applications, this heavy-duty railing base establishes a high-strength, rigid connection that ensures long-term safety and structural stability for balustrades on stairs, balconies, and public walkways. The plate features an 8 mm profile height (H), a total outer diameter (D), three 11 mm pre-drilled mounting holes for surface bolting, and a central bore engineered to fit standard 42.4 mm and 48.3 mm architectural pipes. Manufactured from premium stainless steel grades including AISI 304, AISI 316, and Duplex SS 2205, these versatile handrail fittings are offered in refined satin brushed or mirror polished surface finishes to satisfy both demanding environmental conditions and elevated architectural design standards

Q1: What is the primary application of an 8 mm Welded Base Plate?
A: A Welded Base Plate acts as the core load-bearing interface between a vertical handrail post and a flat mounting substrate. The post is permanently welded to the plate's central opening, creating a unified metal structure that is anchored to walls or floors to support heavy daily traffic.
Q2: What are the key dimensions and mounting specifications of this railing base?
A: This model features a solid 8 mm plate thickness (H), an overall outer diameter (D), and a precision central opening sized for standard 42.4 mm or 48.3 mm pipes. It includes three 11 mm pre-drilled holes, allowing structural anchor bolts to secure the plate firmly to concrete, timber, or steel surfaces prior to covering or finishing.
Q3: How do I select the right stainless steel grade and surface finish for my project?
A: Specification depends on the project location and exposure level:
AISI 304 (Satin Finish): Ideal for climate-controlled indoor staircases, residential halls, and commercial office interiors.
AISI 316 (Satin/Mirror Finish): Highly recommended for standard outdoor balconies, garden decks, and municipal walkways exposed to rain and ambient humidity.
Duplex SS 2205 (Mirror Finish): Formulated specifically for maximum pitting and stress-corrosion resistance in coastal marine zones, beachfront properties, and high-chloride swimming pool environments.
Q4: Can this base plate be used with both welded and bolted surface connections?
A: Yes. The handrail post is fused directly to the plate via welding to form a permanent structural bond. The assembled post unit is then bolted down to the floor or wall using the three 11 mm mounting holes. An optional snap-fit base cover can be placed over the plate to conceal the mounting hardware for a clean visual finish.
