1. General railings (balcony railings, stair handrails) should be installed before painting, so that the fixtures can be hidden by painting after installation.
2. Check the size of the railing in the deepening drawing. Generally, when installing railings, masonry has been completed. At this time, the size of the railing is too long, which makes it impossible for us to transport the railing to the designated location for installation. Should consider the specific construction situation of the construction site; According to the actual situation on site, communicate the size of the railing with the drawing unit that deepened the railing in advance. If the railing is too long, add connectors in the middle for design.
