Product Description
Premium Custom Tempered Glass: Precision Processed for Your Project
As a foundational material for modern construction and furniture, our Flat Tempered Safety Glass offers superior strength and optical clarity. We process high-quality float glass through advanced tempering furnaces, creating glass that is 4-5 times stronger than annealed glass.
Why Buy from Us?
Precision Cutting: We utilize CNC cutting and water-jet technology to handle complex shapes, notches, and hinge cutouts with millimeter precision.
Perfect Edges: From high-gloss flat polish to beveled edges, our finishing ensures safety and aesthetics for frameless applications like shower doors and tabletops.
Versatile Inventory: We stock a wide range of raw glass substrates, including Clear, Ultra Clear (Low Iron), and various Tinted options to ensure fast lead times.

Product Packaging
Strong plywood crates with steel banding.
Individual carton packing available for furniture glass (e.g., table tops) for direct retail.
Cork pads or powder interleaving to prevent friction scratches.

Comment & FAQ
Q1: Can you drill holes for hinges and handles?
A: Yes, we have CNC drilling centers to create countersunk holes and precise cutouts for all hardware types.
Q2: What is the difference between Clear and Ultra Clear glass?
A: Standard Clear glass has a slight green edge due to iron content. Ultra Clear (Low Iron) glass is crystal clear with neutral edges, recommended for high-end displays and light-colored walls.
Q3: What is your MOQ?
A: Generally 1 crate (approx. 100 sqm) ensures the safest transport, but we can discuss specific project requirements.
Q4: How do you prevent glass from breaking during shipping?
A: We use professional A-frame seaworthy wooden crates and load containers compactly to prevent any movement inside the container.
