Ever since 1969, CHA has been an outstanding aluminum window/door manufacturer. Not only does CHA produce durable products, but we also provide appropriate and customized service for clients. Today, CHA occupies a niche market and has earned a good reputation in the aluminum extrusion industry. To achieve the highest value for our customers, CHA will keep on striving for perfection.
In 2006, CHA imported German technology and hence invented BALUK. This product has outstanding insulating capability and keeps indoor comfortable, hence reducing dependence on air conditioning achieving the goal of conserving energy.
In 2009, CHA worked with Japan’s No. 1 construction company, TOSTEM. Through this collaboration, CHA established better techniques and higher standards. Meanwhile respecting the needs of Taiwan’s unique climate; CHA developed Japanese-engineered products that tailor to the needs of the people in the country- DAIWAKI.
All of CHA’s product brands include BALUK and DAIWAKI. Through unique products, CHA has allowed buyers to choose the windows they prefer. Such diversity and technology could be praised as the best in the field.
