Ajilpo sliapeil. or ilnuhir pieic "f Iron, tins no fqiinl for streiiKtli, 

 the ;iu)i»iiiit of iron used being taken into eonsideratlon. 

 When :i slr:ilii is i)rouyIu to l>ear on any part, it Is (ilstrlimted 

 to every part of tlie circle, so that every part Is doing Its part to 

 stand the piessme. 



liased on this engineering fact the U-Bar construction is con- 

 struited. 



The steel part of the U-Bar itself is really a cireie squeezed to- 

 gether a bit and the top cut off, making an oblong shaped mem- 

 ber wliicli, next to a circular shape, is one of tiie strongest 

 shapes. 



This oblong circle of galvanlze<l steel, with its chemically treated 



cypress core bar, makes the complete l"-Har. 



Xow you understand as you never understood before. Just why 



I'-Bar roofs, iiglit as tliey are. are strong as they are. 



The U-Bar, aithotigli no larger than the roof Itar tised in otlier 



constructions, forms b-.'tii the roof bar and rafter In one. 



By using curved eaves other <'onstructions may look like the 



U-Bar — but that Is the only way they ire like It. 



If it is not built with tlie U-Bar It Is not a U-Bar curved-enve 



house. Send for a catalog or send for us— or both.
