Supported Floor Slabs

The use of Welded Wire Reinforcement in supported floor slabs has proven a good choice in many construction projects. The advantages of reduced labor costs in placing the reinforcement, along with knowing the correct amount of steel is in the proper location, are two important reasons for its consistent use throughout the concrete constuction industry.

The engineering analysis provides the amount of steel in both the positive and negative moment areas. Here the engineer has the option of using a higher allowable stress of 80,000 p.s.i., instead of 60,000 p.s.i. to reduce the amount of steel required. Then the type of mesh reinforcement can be selected by choosing the size of wire and the spacing to equal the required steel area. For example ; if the positive moment steel required is .16 sq. in. per foot of slab, then several styles may be selected-- 4x4-W5.4/W5.4 or 6x6-W8.0/W8.0 or even 12x12- W16/W16.

The size of the sheet can be ordered to fit the layout of the building. 8'x20' sheets are standard but other sizes can be ordered to minimize cutting on the job. Although, if the different number of sheet sizes can be kept to a minimum, the project cost may be reduced.

Several of our plants are capable of producing sheets with different length wires in the long direction. This ability can save you a considerable amount of steel by taking advantage of provisions in the "ACI Building Code Requirements for Structural Concrete, "that require only one-third of the positive reinforcement in simple members and one-fourth the positive reinforcement in continuous members to extend into the support. Let our engineers help you with the best selection of sheet size for your job.
