2. Handrail - Wikipedia

   en.wikipedia.org/wiki/Handrail

   Handrails are to support a continuous load of 50 pounds per foot (74 kg/m) or a concentrated load of 200 pounds (91 kg) applied at the top of the handrail. [10] As handrails come in different materials, the strengths can vary. From timber to stainless steel, it is best to pick a handrail that will be right for the area.

3. Hot-dip galvanization - Wikipedia

   en.wikipedia.org/wiki/Hot-dip_galvanization

   Hot-dip galvanization. Hot-dip galvanization is a form of galvanization. It is the process of coating iron and steel with zinc, which alloys with the surface of the base metal when immersing the metal in a bath of molten zinc at a temperature of around 450 °C (842 °F). When exposed to the atmosphere, the pure zinc (Zn) reacts with oxygen (O 2 ...

4. Guard rail - Wikipedia

   en.wikipedia.org/wiki/Guard_rail

   Guard rail. Guard rails, guardrails, railings or protective guarding, [1] in general, are a boundary feature and may be a means to prevent or deter access to dangerous or off-limits areas while allowing light and visibility in a greater way than a fence. Common shapes are flat, rounded edge, and tubular in horizontal railings, whereas tetraform ...

5. Rail profile - Wikipedia

   en.wikipedia.org/wiki/Rail_profile

   Steel is a much stronger material, which steadily replaced iron for use on railway rail and allowed much longer lengths of rails to be rolled. The American Railway Engineering Association (AREA) and the American Society for Testing Materials (ASTM) specified carbon, manganese, silicon and phosphorus content for steel rails. Tensile strength ...

6. Iron railing - Wikipedia

   en.wikipedia.org/wiki/Iron_railing

   An iron railing is a fence made of iron. This may either be wrought iron, which is ductile and durable and may be hammered into elaborate shapes when hot, or the cheaper cast iron, which is of low ductility and quite brittle. Cast iron can also produce complicated shapes, but these are created through the use of moulds of compressed sand rather ...

7. Structural steel - Wikipedia

   en.wikipedia.org/wiki/Structural_steel

   Structural steel. Structural steel is a category of steel used for making construction materials in a variety of shapes. Many structural steel shapes take the form of an elongated beam having a profile of a specific cross section. Structural steel shapes, sizes, chemical composition, mechanical properties such as strengths, storage practices ...
