(4) Perfect distribution of Steel. Every foot of width possesses the theoretical amount of 

 steel. The accuracy hore attained is inconceivable in loose rod reinforcement. Misplaced rods, 

 even to a slight extent, increase the working stresses in part of the steel. Unit stresses that the 

 specifications rigidly state must not exceed 15000 or 16000 Ibs. per sq. in. in the calculations, 

 in practice easily exceed 20000 and even 30000 Ibs. per sq. in. by occasional grouping' of loose rods 

 or bent and twisted wires in a mesh. 



(5) Longitudinal reinforcement. The sub-soil of sewers and conduits invariably possesses soft 

 spots or even holes. " Steelcrete " mesh possesses strength in the longitudinal direction of the 

 pipe equal to one thira the strength in the circumferential direction. The theoretically correct 

 amount in the longitudinal direction can never be known. This reinforcement automatically 

 provides a liberal amount ample to take care of any normal condition. 



(6) Temperature stresses are guarded against. These are sure to be encountered and must be 

 provided for. Temperature cracks mean leaky construction. The form of the mesh provides a 

 positive reinforcement against these uncertain but definite stresses. 



Practical (7) "Steelcrete" mesh is essentially a fool-proof reinforcement. With the use of this material 



Considerations. the man with the brains that designs the construction obtains from the unskilled laborer, to whom 

 theoretical considerations are as meaningless as Sanskrit, an efficiency ot 100 per cent with 

 ordinary every day inspection. 



(8) "Steelcrete" Mesh is a stiff reinforcement. It holds its position in the forms in a way 

 that no other mesh equals. As the shape of the fabric provides a perfect distribution of the steel 

 in a horizontal direction or in the plane of the sheet, so its stiffness insures a like perfect distribu- 

 tion in a vertical direction or in a direction at right angles to the plane of the flat sheet. In 

 other words, it lies taut in place. No waves or warps to be hammered out or offer elements of 

 weakness. Some fabricated wire reinforcements advertise the fact that the joint between the 

 cross-wire and the main longitudinal wire is a hinge, i.e., will permit the buckling of the sheet in 

 a vertical direction. This may be an advantage in some structures but it can be nothing but a 

 detriment to a fabric to be used in sewer work or in flat floors. Engineers will be found to be 

 unanimous in agreeing that it is far more important to have the reinforcement placed correctly 

 in a vertical direction than in the horizontal. In this respect " Steelcrete " mesh is unequaled.
