Corrugated studs also named umbrella head roofing nails are fasteners designed to connect wood components and secure roof tiles, mainly thanks to their signature large caps. I have sorted out its core features and applications for you:
Core features:
* Anti-corrosion and durable: Usually made of mild steel, the surface will be galvanized or polished, which has strong rust resistance and can cope with outdoor wind and sun.
* Firm grip: The nail bar has a variety of designs such as ring pattern and spiral, which can bite the wood tightly like a screw, and is more resistant to loosening than ordinary round nails.
* Protective surface material: The round cap is its hallmark, which can increase the contact area, disperse the pressure, and effectively prevent asbestos tiles or plastic tiles from being nailed and cracked.
* Efficient installation: In addition to single nails, there are also roll nails, which can be quickly installed with tools, which is very suitable for large-area roof construction.
Main applications:
* Building roof: mainly used to fix asbestos tiles, plastic tiles, and metal tiles on wooden purlins or roofs.
* Wooden engineering: It is also suitable for the connection of wooden components, such as building wooden structures, installing window frames, etc.
* Other fields: It can also be found in furniture manufacturing (e.g. frame splicing) and packaging industry (e.g. reinforced wooden boxes, pallets).
Common specifications
The specifications of corrugated nails are usually expressed in terms of diameter and length, and the following are common parameters for your reference:
Items Common parameter ranges
Nominal diameter 2.8 – 4.2 mm
Length range 38 – 120 mm
Surface Treatment Galvanized (electroplating/hot plating), polished
Nail rod type: bare body, ring pattern, spiral, square
Are you planning the construction of the roof, or are you sourcing materials? Tell me the specific corrugated board material (such as cement tile or color steel tile) and the fixed base layer (such as wood or steel beam), and I will help you calculate how long and thick nails are most suitable.
