Re: type of iron of metallic bridges Acrow panel

[Subject Prev][Subject Next][Thread Prev][Thread Next]
For an authoritative answer, you should contact ACROW Corporation of
America.

There are at least three systems that may be "generically" referred to as
ACROW bridges, 1) the predecessor "Bailey Bridge" system, 2) the ACROW 300
series system, and 3) the current ACROW Panel 700 XS system.   The material
properties differ accordingly.

The channel sections of the main chord members of the most common ACROW  300
series were made to BS4360 Grade 55C (British Standard).  The other
components are of varying materials.  The pins were a chrome moly steel
conforming to BS970 Type 208 M40 grade T, similar to the mechanical
properties of ASTM A193 B7, with a rated capacity of 146,000 lbs (US) in
double shear.
