"STEELCRETE" EXPANDED METAL AND THE DECIMAL 



STANDARDS. 



In order to permit our varying sizes and weights of material to be of . most use, we have 

 recently .adopted a scale of sizes based on the decimal system, using the cross-section per ft. of 

 width as the basis for the change. A close inspection of this system will- show the great advan- 

 tage offered by this scheme. The change will appeal in particular to engineers or designers who 

 have to deal with and care only for sectional area per ft. of width. 



In our new method all our standard meshes have a diamond 3 inches by 8 inches, as be- 

 fore. The designation of the material describes the size of the diamond, ' the gauge of the 

 plate and the cross-section per ft. of width; i. e., Size 3 9 15 means that it is a 3 inch diamond, 

 made out of No. 9 plate, having a sectional area per ft. of width of .15 sq. in. Our special 

 meshes carried in stock have a diamond of YA,, \ l / 2 and 2 inches in the short direction. We also 

 make to order a 6 inch mesh, th.e size of the diamond being 6 inches by 16 inches. The gauge 

 of plate used is No. 4, or nearly J4 mcn thick. Any cross-sectional area desired up to and includ- 

 ing 0.4 sq. in. will be furnished. The width of the sheets will depend on the sectional area. 



We also make a 4 inch mesh from No. 16 plate, which is unexpanded. We furnish this in 

 any length up to 16 feet. The cross-sectional area per ft. of width is .093 sq. in. 



It is well to note the special meshes, such as the 34 inch, \]/ 2 inch and 2 inch, are not 

 used in concrete reinforcement except in very special cases, when unusual conditions exist. 



EMBODY THIS IN YOUR SPECIFICATIONS. 



The slabs shall be reinforced with "Steelcrete" Expanded Metal, size 



(or The slabs shall be reinforced with "Steelcrete" Expanded Metal of such a thickness of 



slab and size of metal as shall carry a superimposed load of Ibs. per sq. ft. with a 



factor of safety of 4). 



The Expanded Metal shall be laid on the forms with long way of diamond meshes extending 

 transversely to supporting beams. Adjoining sheets shall be lapped eight inches on the end and 

 one and a half inches on the side. They shall be wired together every three feet on the ends and 

 every four feet on the sides.
