Calaca Works


Phoneix Petroterminal & Industrial Park, Calaca Batangas, Region 4A (Southern Luzon)


The Calaca Works of SteelAsia houses a mini-mill or an integrated rebar line.  The rebar line is directly integrated with its own scrap-based billet production. The mill was established by BSII in 1999.  It mothballed a year later soon after the 1997 Asian Financial Crisis and acquired by the SteelAsia group in 2007.  After rehabilitating and upgrading the facility, it was and re-commissioned in 2008.  We call this manufacturing line M3.

M3 is unique because it is only integrated steel works in the Philippines.  M3 has steelmaking capability.  It recycles domestically purchased steel scrap which it melts and casts into semi-finished steel called billets.  The unique feature of this process is that the steelmaking is linked to the rolling. Newly cast red hot billets are charged into the rolling mill facility.  The process, which is called direct hot charging saves up to 40% on fuel consumption, compared to simply buying and feeding cold billets into the rebar line.  The mill also features a twin high-speed tungsten carbide monoblock.  M3 was the first mill to use this technology and it gave it the ability to produce small rebar sizes with high precision while maintaining speed and productivity.

It featured many other modern technologies such as an in-line rolling train configuration, independent drives, Level-2 automation, quick size change among others, and these brought the mill to world standards of productivity, conservation and operational health and safety. 

Originally commissioned as a 300,000 tpy mill, SteelAsia has upgraded its equipment and technologies to its current capacity of 500,000 tpy. 

M3 is located in an industrial park with its own port.  This logistic feature improved service to Visayas and Mindanao consumers of rebar.  Though M3 primarily serves Region 4 customers, it continues to be an able back-up during spurts of rebar requirements of construction projects in Metro Manila and the southern islands of the Philippines.
