■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 fireproof ceiling inspection openings, 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-manufactured box-shaped fireproof coating above the ceiling inspection opening; however, these measures can become a burden on 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 that comply with 45-minute quasi-fireproof structures, the visible width has been narrowed, and the base material has been painted for a cleaner appearance. ■Consideration for Safety During Opening, Closing, and Inspections Since ceiling materials become heavier in 60-minute quasi-fireproof structures or reinforced ceilings, a fall prevention chain is standardly equipped to prevent the lid from opening too forcefully during inspections. ■Special Column Published 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↓
