■Ensuring the Continuity of Fireproof Coating The fireproof performance of our conventional products (made of aluminum) is approximately 28 minutes (based on our test values), so it is conceivable that continuity of fireproof coating cannot be ensured in quasi-fireproof structures or reinforced ceilings. By using a fireproof ceiling inspection opening, continuity of fireproof coating can be secured. ■Simplification of Construction To ensure the continuity of fireproof coating, there are cases where various methods are employed, such as installing a site-fabricated box-shaped fireproof coating above the ceiling inspection opening, but these measures can burden the site. This product eliminates the need for a box-shaped fireproof coating, leading to a reduction in on-site construction effort. ■Slimming Down the Visible Width for Aesthetic Appeal Compared to products compatible with 45-minute quasi-fireproof structures, the visible width has been made narrower, and the base material has been painted for a cleaner appearance. ■Consideration for Safety During Opening, Closing, and Inspections Since the ceiling materials for 60-minute quasi-fireproof structures or reinforced ceilings are heavier, a fall prevention chain is standardly equipped to prevent the lid from opening forcefully during inspections. ■Special Column Now Available by Mr. Noboru Yasui, Representative of Sakura Design Group, First-Class Architect Office "What are the important points regarding fireproof coating required for quasi-fireproof and fireproof buildings?" ↓Click the related link↓
