PRODUCT

504.8g Embedded Steel Plate Base for Handrail Installation, Two-Hole Design A-05

The 504.8g Embedded Steel Plate Base is a structural mounting component engineered for the secure anchoring of handrail systems and architectural balustrades. Manufactured from carbon steel with a precision-weighted profile of 504.8 grams, this base plate provides the necessary mass and surface area to distribute mechanical loads across concrete or masonry substrates. The two-hole design is specifically configured to accommodate heavy-duty expansion bolts or chemical anchors, ensuring lateral stability for upright posts. This embedded plate acts as the primary interface between the architectural finish and the structural foundation, preventing post-oscillation and maintaining vertical alignment under rotational torque.

504.8g Embedded Steel Plate Base for Handrail Installation

Technical Specifications and Core Advantages

  • Weight-Calibrated Stability: The 504.8g mass ensures a low center of gravity and sufficient material thickness to prevent plate warping during high-torque bolt tightening.
  • Optimized Two-Hole Configuration: The dual-aperture layout allows for streamlined installation in narrow mounting surfaces where traditional four-hole bases cannot be accommodated, without compromising pull-out resistance.
  • Load Distribution: The flat-bottom surface increases the contact friction against the substrate, reducing the shear stress on individual fasteners.
  • Compatibility: Designed for standard diameter handrail posts, the plate can be integrated with both welded and sleeve-connected uprights.

Application Scenarios

  • Industrial Safety Rails: Securing safety barriers in warehouses and manufacturing facilities where floor space for mounting is restricted.
  • Architectural Balustrades: Installation of stainless steel or glass handrail posts on residential balconies and commercial staircases.
  • Infrastructure Projects: Mounting of guardrails on pedestrian bridges, ramps, and public walkways.
  • Urban Furniture: Anchoring of bicycle racks, bollards, and lean-to railings in public transit zones.

Installation and Storage Guidelines

Storage Conditions

To prevent surface oxidation, store the steel plates in a low-humidity environment. If the plates are not galvanized, keep them in their original VCI packaging or apply a light coating of industrial oil. Avoid direct contact with acidic or corrosive chemical agents during transport and warehousing.

Usage and Safety Notes

  • Substrate Integrity: Ensure the concrete or masonry surface is fully cured and free of cracks before drilling for the two-hole anchor points.
  • Torque Requirements: Use a calibrated torque wrench to tighten fasteners to the specific kilonewton (kN) rating required for the handrail's height and expected load.
  • Anti-Corrosion Maintenance: For outdoor installations, inspect the base plate edges and bolt heads periodically for signs of rust, especially in coastal or high-salinity environments.
