Perforated Plate HP 180x220x1.5mm Hot-Dip Galvanized Steel 25pcs Fast 833346

Robust 180x220x1.5 mm perforated plate made of hot-dip galvanized steel, designed for high strength in timber structures and for joining roof trusses.

Description

HP perforated plates are an essential component in all types of modern timber construction, where high standards for stability, safety, and long service life are required. This model measures 180x220x1.5 mm and is produced to ensure a precise fit and consistent quality in every connection. By using top-grade hot-dip galvanized steel, the component gains excellent protection against external stresses, making it suitable for both indoor environments and more exposed construction projects. The design features a carefully stamped plate with a dense pattern of round nail holes, which facilitates installation and ensures an even distribution of load across the timber.

Applications and Structural Advantages

These perforated plates offer a wide range of uses in demanding construction projects. These are primarily used as connector plates for assembling roof trusses, load-bearing wall structures, frameworks, and other critical connection points in timber buildings. To achieve optimal results and avoid eccentric loading at the joint, it is recommended to always use two identical plates per connection, positioned on opposite sides of the timber element. The symmetrical load transfer achieved in this way prevents skewed loading and ensures that the entire structure maintains its geometric stability over time, even under heavy snow or wind loads.

Material and Corrosion Protection

The material used for manufacturing is hot-dip galvanized steel sheet (grade S250GD) with a Z275 zinc coating. This zinc coating provides effective sacrificial protection, preventing rust and oxidation even if the plates are exposed to damp environments or varying weather conditions during the construction phase. The S250GD steel grade ensures the ideal balance of high yield strength and good formability, preventing the plates from deforming or cracking under load or during installation. With a robust thickness of 1.5 mm, the plates are highly rigid, resisting bending and effectively holding timber components together in demanding structural applications.

Installation and Fastening

To ensure that a connection achieves its calculated load-bearing capacity, it is crucial to select the appropriate fasteners and install them in a professional manner. The nail holes have a diameter of 5.0 mm, designed to accommodate standard connector nails or connector screws. For fastening, use 4.0 mm anchor nails or 4.8 mm anchor screws to ensure the holes are filled correctly without any play. As a general rule, all available nail holes in the connection should be filled—unless otherwise specified in the particular structural drawing—to ensure effective load transfer between the steel plate and the timber frame.
