rebar companies in southern California
Before you start looking for rebar companies in Southern California for your rebar supplies, it is important to know what to look for when choosing rebar. The construction of a house needs different types of materials and that is why you should be very careful when choosing rebar. You should do adequate research before buying rebars. Rebars are very important for the life of your structure. Consider the following tips when choosing the right rebar for your project.
Mild steel bars
These are plain on the surface. They are round sections of diameter from 6 mm to 50 mm. Mild steel bars can be manufactured in long lengths and they bend easily without any damage. They can also be cut quickly.
High strength deformed steel rebars
These are provided with ribs, lugs or deformation on the surface of the rebar to improve the bond with concrete. High strength deformed rebars are also twisted to improve the bond with concrete. They are recommended as the best quality rebar for construction.
Why should you purchase steel bars?
Steel rebars are needed to reinforce the RCC structure. Using concrete alone doesn’t help since concrete is weak in tension and strong in compression. Rebar is used to compensating for the imbalance to provide increased tensile strength. You have to choose the right grade and type of rebar depending on your requirement or as considered in structural drawing by the structural engineer. If you don’t know the right of steel you need for your project, you can consult with rebar companies or a structural engineer.
Quality and specification of rebar
Purchase only the grade of rebar that is prescribed in the drawing. You should check the identification mark on the rebar from the manufacturing company. The identification mark is marked at every running meter of the rebar length. There shouldn’t be any rust film on rebar. You should always purchase rebar that is rust free. Make sure you check the diameter for the rebar using the vernier caliper and it should be the same as what is specified in the drawing.
Readymade cut bars
In advanced countries, people do not purchase steel. They purchase ready-made bars as per the designed shape and length. All you have to do is to place them in position. However, it is important to check the length and shape of each type of rebar as per the bar bending schedule, check the hooks, their length and shape, check numbers and stack each rebar separately and check the quantity.
Steel rolling margin
You should check the rolling margin in the weight of the rebar. Rolling margin is important when you purchase rebar in tons and you are paid in lengths. You should avoid using rebar from those rolling mills that use scrap steel or rerolled as row material. They are likely to have a high carbon content which is prone to corrosion. Ask for the chemical composition from rebar companies in Southern California. Apart from other materials, the carbon content is very important. It shouldn’t be more than 0.25% as it would speed up corrosion.
