This copy of Steel Construction, a reference manual published in 1948, is the 5th Edition, 6th Printing, and is intended for use by Architects and Engineers. The information in this manual doesn't change very often and is an excellent resource for students and professionals alike. Great for use or great for office decor. There is also a lettering lesson included. Please review the photos and email me with any questions BEFORE bidding, purchasing, or making an offer. I try to respond as quickly as possible, but please allow up to 24 hours for a response. If you purchase more than one item, let me invoice you with an updated total and combined shipping.
