Black steel roof3/21/2023 ![]() ![]() This is an economical system, very quick to install, ideal for short runs where expansion and contraction are not a concern.Īs the snap lock system, this system relies on the rigidity of the material used, therefore softer materials such as copper are not recommended. This system snaps together just like a Snap Lock system and has a hidden built –in nail strip that eliminates the need for cleats. The Nail Strip Lock system is offered in 1” and 1.5” high seams. Snap lock panels cannot be curved.īecause this system relies on the rigidity of the material used, softer materials such as copper are not recommended. Snap Lock also incorporates fixed or expansion cleats that allow the panel to expand and contract. Snap Lock eliminates the need to mechanically lock the seams together, allowing for a much faster installation, much easier for those looking for a DIY project. This system snaps together as the panels are installed. The Snap Lock seam is offered in 1” and 1.5” high seams. These panels are secured to the roof deck via roof clips and can be curved. ![]() Commonly used materials are copper, lead coated copper, freedom gray, zinc, and Kynar coated steel and aluminum.Ĭopper based systems offer the advantage of being able to be soldered where needed, where aluminum systems are easier to work with and more malleable, while Kynar steel systems are a more tough panel, although not recommended for installations near the ocean. The double lock has long been considered the best locking system available and is it not uncommon to find century old systems still functioning properly. This profile panel is available in 1” or 1.5” high standing seam.

The difference between carbon steel and black steel is that carbon steel requires galvanization because it is susceptible to corrosion whereas black steel is made from non-galvanized steel. Requires galvanization because this steel is susceptible to corrosion.Ĭarbon steel and black steel contains irons along with some other constituents. The black steel has high strength and hardness. The hardness of carbon steel depends on the carbon content. This steel is important in applications where galvanized steel is not required.Ĭarbon steel is a form of steel containing carbon as a major constituent.īlack steel is non-galvanized and has dark-coloured iron oxide coating on the surface. The name “black steel” comes due to the appearance of the steel it has a dark color on the surface of the steel due to iron oxide coating. What is Black Steel?īlack steel is a form of non-galvanized steel. That is because of its high strength and hardness that makes it difficult to cut and weld. High carbon steel has a very high amount of carbon content around 0.61-1.50% by weight. Therefore, it is difficult to cut and weld this steel. This form is stronger and harder than low carbon steel. It also contains a considerable amount of manganese. ![]() Medium carbon steel has more carbon than low carbon steel usually around 0.31-0.60% by weight. Other components such as aluminium are added to enhance the properties of the steel. For many applications, this form of steel is useful. Low carbon steel or mild steel contains a less amount of carbon, typically around 0.04-0.30% by weight. There are three major types of carbon steel as follows: ![]()
