2. I-beam - Wikipedia

   en.wikipedia.org/wiki/I-beam

   I-beams are still available in US sizes from many Canadian manufacturers. In Mexico, steel I-beams are called IR and commonly specified using the depth and weight of the beam in metric terms. For example, a "IR250x33" beam is approximately 250 mm (9.8 in) in depth (height of the I-beam from the outer face of one flange to the outer face of the ...

3. List of steel producers - Wikipedia

   en.wikipedia.org/wiki/List_of_steel_producers

   The World Steel Association features a list from its members every year. Due to mergers, year-to-year figures for some producers are not comparable. Not all steel is the same. Some steel is more valuable than other steel, so the volume is not the same as turnover. Some of the world's leading steel producers include China Baowu Group and ...

4. ASTM A992 - Wikipedia

   en.wikipedia.org/wiki/ASTM_A992

   ASTM A992 steel is a structural steel alloy often used in the US for steel wide-flange and I beams. Like other carbon steels, the density of ASTM A992 steel is approximately 7850 kg/m 3 (0.2836 lb/in 3). ASTM A992 steel has the following minimum mechanical properties, according to ASTM specification A992/A992M.

5. Structural steel - Wikipedia

   en.wikipedia.org/wiki/Structural_steel

   Many structural steel shapes take the form of an elongated beam having a profile of a specific cross section. Structural steel shapes, sizes, chemical composition, mechanical properties such as strengths, storage practices, etc., are regulated by standards in most industrialized countries.

6. Prefabricated building - Wikipedia

   en.wikipedia.org/wiki/Pre-engineered_building

   In pre-engineered buildings, the I beams used are usually formed by welding together steel plates to form the I section. The I beams are then field-assembled (e.g. bolted connections) to form the entire frame of the pre-engineered building. Some manufacturers taper the framing members (varying in web depth) according to the local loading effects.
