Does Baosteel, Angang, Masteel and Laigang refer to steel products or company names? Why is it called Baosteel Masteel?

I know this. Baosteel, Angang, Maanshan Iron and Steel Co., Ltd. and Laigang Co., Ltd. are all named after the area where the steel mills are located.

Baosteel: It's in Baoshan District of Shanghai, so it's called Baosteel.

Angang: It's in Anshan, Liaoning, so it's called Angang.

Maanshan: It is called Maanshan in Anhui.

Laigang: It's in Laiwu, Shandong. It's called Laigang.

Most large state-owned steel mills are named after their initials, and some private enterprises are named by themselves!
