Everyone should have a comfortable place to live, work and play.


"Everyone should have a comfortable place to live, work and play", the company philosophy conveyed exactly the hope of YC Wong, who is the founder of Castwell Industries (M) Sdn Bhd, a pioneer builder specializes in IBS and modular building construction system in Malaysia.

Graduated from the University of Portsmouth in UK with the Bachelor of Engineering (Hons) Degree, the founder started his career with an outsource company as a Sales Engineer in year 1998. It was the same year when the economy crisis happened and caused a lot of challenges to Wong however these are what he is appreciate today because he treats challenge as an opportunity to success. So “think out of box”, this is what the founder always advised.

There were some personal belief built-up through Wong's experiences over the years and they were later turned into the company core values as Castwell established:-

Strength, we must keep strengthen our self and grow;
Persistence, we should never afraid of challenges and failures;
Patience, we must believe in our own capabilities; and
Excellence, we must strive to be the best.

Now, Castwell has been well-known in the Government sector for its construction systems under the lead of Wong, the next company goal is set to enter the private sector with the intention to turn Wong’s personal hope, which now serves as the company philosophy, into reality.
