Storage of Construction Material- Steel Bars, Cement, Bricks & Aggregate At Construction Site

Storage of Construction Materials (Steel Bar) at Construction Site. As we know that steel bars cover 25 -30% of the overall cost of the building so it is very crucial that steel bars must be handled and stored with precaution on the site. There are different processes or operations where laborers need to take care of steel bar such as unloading, Stacking, Cutting, Bending, Fabrication, etc. Reinforcement has the capability to resist lateral forces and provide strength and ductility to the buildings, so it is very necessary that all these loading and unloading operations should be done properly on site.…

What is Truss? Components of Truss

What is Truss? Truss is a structural member which is in the form of a triangle and connected together with pin joints. All the external forces (loads and reactions) must be applied only at either end of the member, resulting in either compression or tension force. All the joints in the truss members have pinned connections such that no shear or moment forces are transfer from member to member. Truss members are in the form of either tension or compression. Components of Roof Truss Span of Truss It is the distance between the Span of the two supports (i.e. Metal…

What is Galvanized Wire and Its Applications

Galvanized Wire and Its Applications Galvanized is a type of wire which is manufactured under the chemical process of galvanization. Galvanization is the chemical process in which zinc coating is done to steel or iron in order to prevent rusting. It is the most commonly used method of protecting rust from iron. It is manufactured with low carbon steel, having high tensile strength. Its thickness is measured in a Gauge. Zinc coating protects the surface from corrosion and weathering. The main disadvantage of galvanization is pointed below: Basically, it only protects the surface from corrosion for a short period of…
