Heavy duty fasteners are used in construction for wall and roof sheathing, cedar shake shingle siding, for securing framing and I-joists, for binding corrugated boxes and for fastening small cables. Staples have various uses in the construction of a building and this is why it is important for them to have a great durability. When it comes to fasteners, there are plenty of options and alternatives available on the dedicated market. People who wish to use the highest quality staples usually pick stainless steel staples. The coating of the fastener usually dictates its features such as resistance to corrosion and price. Depending on their needs and budget, people usually choose one of the following types of staples: Bright fasteners Bright staples are called those fasteners that have no coating, thus the steel remains unprotected and they are prone to corrosion. When exposed to high humidity levels or directly to water, this type of staples corrodes in a matter of time and need replacement. This is why they are generally used for interior framing and finish applications. Heat treated staples This type of fasteners is made by heating up the steel and then cooling it down immediately. This interlay of extreme temperatures creates steel that is very hard and that can be used without problems on concrete and masonry. However, this technique of creating staples does not offer protection against corrosion, so they are recommended strictly for interior use. Hot dip and electro galvanized fasteners The staples are coated with a sacrafical layer of Zinc that are designed to protect the steel from corrosion. The difference between hot dip galvanized (HDG) and electro galvanized (EG) fasteners is simple: the EG ones have a thinner layer of Zinc making them great for interior use in rooms such as bathrooms where there is a relatively high level of humidity, while the HDG offers a thicker layer of Zinc where steel is “dipped” into a vat of molten Zinc to make them suitable for exterior applications. HDG and EG fasteners will corrode over time, and their durability depends on the thickness of the Zinc. However, HDG collated staples does not exist because of manufacturing limitations and designed capacity to shoot in a stapler. So the EG type of staples are marginal at best. Stainless steel fasteners Stainless steel is one of the best choices in terms of staples, because this alloy is of solid material and not a coated fastener. Stainless steel is resistant to corrosion and has a very high durability. Because it offers one of the best protections against water and high humidity levels without being too pricey, stainless steel staples one of the best choices available on the market. Top-grade stainless steel alloy contains chromium. This secret ingredient offers the resistance to corrosion because it creates a thin layer of chrome oxide in presence of oxygen and the oxide protects it against water and humidity even after the surface gets scratched. Stainless steel fasteners are used in both exterior and interior applications with success. Vinyl coated staples The vinyl coating has only one purpose: to make the staple easier to drive. The coating takes advantage of the fact that fasteners heat up while being driven. After cooling down, the vinyl becomes hard again and is fixed in place. This type of coating does not offer protection against corrosion and is only used for interior applications.
