Two basic types of coils are used: one with coils in spiral form, usually with a cord running inside the coils; the other with coils in ladder form ...
When decks are painted for protection against wear and corrosion, non-skid may be formed by either mixing a granular material like sand into the paint prior to application, or by sprinkling dry sand onto a newly painted surface before the paint hardens by drying or curing.
In the paint and coating industries, paint adhesion testing is often used to determine if the paint or coating will adhere properly to the substrates to which they are applied. Several tests measure the resistance of paints and coatings from substrates: cross-cut test, scrape adhesion, pull-off test , and others.
A major technological change came in 1950, when the company purchased a chain machine from the U.S. that allowed the automation of the zipper making process. Previously, YKK zippers were made by hand, and hence had an inferior quality compared to automated zippers from abroad. In March 1951, YKK relocated its headquarters to Chūō, Tokyo.
A water-based primer, used primarily on wood. A primer (/ ˈ p r aɪ m ər /) or undercoat is a preparatory coating put on materials before painting.Priming ensures better adhesion of paint to the surface, increases paint durability, and provides additional protection for the material being painted.

A phosphate coat is necessary to protect the body against corrosion effects and prepares the surface for the E-Coat. The body is dipped into the Electro-Coat Paint Operation (ELPO/E-Coat), then a high voltage is applied. The body works as a cathode and the paint as an anode sticking on the body surface. It is an eco-friendly painting process.
Sliding glass door frames are often made from wood, aluminum, stainless steel, or steel, which also have the most strength. The most common material is PVC plastic. Replacement parts are most commonly needed for the moving-sliding parts of the door, such as the steel rollers that glide within the track and the locking mechanisms.
