When selecting galvanized perforated metal sheets, the following factors should be considered comprehensively based on the specific application (such as screening, protection, decoration, sound absorption, etc.): Material (e.g., galvanized sheet, stainless steel sheet), sheet thickness, hole size, hole type (e.g., round hole, square hole, etc.), and arrangement. High-quality galvanized perforated metal sheets should have a flat surface, be sturdy and durable, easy to process and install, have good sound absorption, and a long service life.
Taking perforated steel sheets for building scaffolding protection as an example, the common specifications are 1.2m (width) * 1.8m (height). Before installation, a pre-assembly design should be carried out according to the building's shape and scaffolding dimensions. A top-support, bottom-hook fixing method is usually adopted, with connectors installed in groups (e.g., horizontal spacing 0.8m, vertical spacing 1.8m). During installation, the lower end of the perforated sheet is placed on the upper flat end of the connector, and the upper end is hooked tightly with the lower end of the connector. After the scaffolding is erected, such protective measures must be installed promptly to prevent the risk of falling objects from heights. For perforated panels used for indoor sound absorption and decoration (such as micro-perforated metal sound-absorbing panels), snap-on installation methods such as connecting rods to Z-shaped keel brackets are commonly used.
