Perforated Plate HP 80x300x1.5mm Hot-Dip Galvanized Steel 50pcs Fast 833319

Description

The HP 80x300x1.5 mm perforated plate is an essential component for modern timber construction, where high load-bearing capacity and long-term durability are required. This versatile connecting plate is specifically designed to join and reinforce timber elements across a wide range of building projects—from minor renovations to large-scale roof truss assemblies. Crafted from high-quality hot-dip galvanized steel, it offers excellent protection against external stress and corrosion, making it a reliable choice for both indoor and outdoor applications.

Features and Material Quality

The product is manufactured from hot-dip galvanized steel sheet (grade S250GD+Z275). This means the steel is coated with a robust layer of zinc, which effectively prevents rust—even when exposed to damp environments. With a material thickness of 1.5 mm, this perforated plate offers an optimal balance between rigidity and workability. The plate features uniformly spaced nail holes with a diameter of 5.0 mm, ensuring stable and even load transfer across the entire joint when installed with the appropriate fasteners.

Applications in Building and Construction

Perforated plates are primarily used as connector plates for joining roof trusses, studs, and other load-bearing timber components. Their versatile 80x300 mm format makes them ideal for connections requiring additional joint strength. Structures subject to wind loads, snow loads, or significant dead loads benefit greatly from the extra stability provided by these plates. They are equally effective in roof trusses and wall assemblies, as well as in the construction of frameworks for conservatories, decks, and sheds.

Installation Instructions for Secure Joints

To achieve maximum load-bearing capacity and prevent eccentric loading within the timber structure, always use two plates per joint—one on each side of the connection. Proper fastening is essential for the longevity and safety of the structure. For installation, it is recommended to use 4.0 mm anchor nails or 4.8 mm anchor screws, which fit precisely into the pre-punched holes. Ensure that all designated holes are filled with approved fasteners to achieve full structural strength in accordance with applicable building codes.

Advantages of hot-dip galvanized steel

The hot-dip galvanized finish provides exceptional corrosion resistance. The zinc coating works in tandem with the steel to form a protective barrier that withstands moisture, rain, and varying weather conditions. This minimizes the risk of the structure weakening over time and ensures that the joints remain fully functional throughout the entire lifespan of the building. Furthermore, the high yield strength of the S250GD-grade material helps the metal resist deformation under high stress.

Tips for maintenance and storage

To ensure that the perforated plates retain their full corrosion protection while stored on the construction site, they should be kept in a dry location, protected from direct ground moisture and prolonged exposure to precipitation, prior to installation. If the plates are cut or otherwise modified on-site, it is recommended that the exposed edges be treated with a zinc-rich coating to maintain the integrity of the rust protection across all parts of the joint.
