THE BEST DESIGN EVER CREATED WHEN WE BREAK THE NORM

GRANTS is the flagship series of luxurious doors from TOSTEM. It is specifically designed for high-rise buildings.

The innovative design of the slim but strong door frame results in a larger surface area of glass, taking the standard of aluminum windows and doors to another level. It is beautiful with a slot in the door frame to keep the door out of sight when closed, giving a panoramic view to the residents.

The door is highly convenient and practical as it is manufactured with modern technology. Certified with international standard ASTM, the product delivers utmost reliable and performances.
