Note:

HIPCO Structural steel pipes are made in the same way as other pipes, however the steel used is of higher yeild/ tensile strength which reduces the steel consumption considerably. Structural pipes are mostly used for making welded structures, towers, poles, etc.

  1. Ref standard NS 427-058 IS 1161-1979, BS 1387, JIS-G-3444-1993
  2. Yield strength as per various standards varies from 170 MPa to 400 MPa, for high tensile material requirement details and prices available on request
  3. L-Light, M-Medium, H-Heavy
