As Malaysia’s premier steel bar manufacturer, Malaysia Steel Works (KL) Bhd began its operations in 1971, producing commercial grade mild steel round bars and ingots at its rolling mill in Petaling Jaya, Selangor Darul Ehsan, Malaysia.
A Star is Born

Malaysia Steel Works (KL) Bhd ("Masteel") was founded on 25th of March 1971 by the Tai Family which were helmed by the late Mr Tai Chet Siang and Dato' Tai E King J.P.

Masteel was the first Malaysian operator of electric arc furnace to smelt steel scrap to produce steel bars for use in reinforced concrete.

It also operated a reversing mill to roll steel ingots into steel bars.

Masteel Upgraded

In 1997, the Petaling Jaya mill was further upgraded to become a fully continuous mill together with the addition of a new reheating furnace that could utilise 1 ton billets.

The capacity of the mill was subsequently upgraded to 450,000mt per year. A thermo quenching line was installed to produce grade 500 deformed bars to meet the ever-increasing demand of our customers. In December 1997, the mill obtained the ISO 9001 certification in recognition of its commitment and dedication to quality management system.

Masteel Commissioned a New plant - Meltshop in Bukit Raja

In 1998, a new milestone in the history of Masteel was realised when its new Meltshop in Bukit Raja went into commercial production. The billet production plant supplied by Danieli of Italy became one of the most modern meltshop in operation in the ASEAN region. The electric arc furnace is featured with ultra-high power [UHP] transformers, eccentric bottom tapping (EBT) configuration and fully automated furnace process control and alloy additive plant.

A refining ladle furnace was also added to increase the output & quality of steel billets produced.

A multi-stand large curvature continuous casting machine which could cast high-grade billets up to 160mm x 160mm was also installed. The installed capacity of the Meltshop is 750,000mt of billets per year.

Masteel Listed in Bursa Malaysia

In 2005, Malaysia Steel Works (KL) Bhd ("Masteel") was listed on the Malaysian Stock Exchange ("Bursa Malaysia"). Masteel joined ranks of top publicly traded steel manufacturers in the Asean region.

Masteel Upgraded

In 2015, Masteel completed the construction of its 2nd rolling mill of 300,000mt capacity at Bukit Raja specialising in prime grade small diameter steel bars.

The quality control laboratory of the Meltshop is equipped with state-of-the-art testing equipment such as automated spectrometer.

The high consistency of the quality billets produced by its Meltshop has further consolidate the position of the Company as one of the principal steel bars and steel billets manufacturer in ASEAN region.

Masteel Transforms

In 2021, Masteel completed its 4 years revamping programme of its steel making facilities by installing new ultra-low emissions 60mt induction melting furnaces to replace its conventional electrical arc furnace.

These new furnaces are able to produce both carbon and alloy steel.

Masteel Goes Green

In 2022 Masteel successful installed and commissioned its new billet direct charging technology that eliminates the use of fossil fuel for billet reheating at its Bukit Raja rolling mill.

Masteel raises industry benchmarks as the 1st ‘ultra low carbon emission’ integrated steel mill in Malaysia. And also the 1st integrated steel mill in Malaysia to be included as a constituent of the FTSE4GOOD Bursa Malaysia Index in December 2022.
