What is a temperable mirror (toughenable mirror) and what are its main advantages?
A temperable mirror is a specialized coated glass manufactured via offline vacuum magnetron sputtering technology. Unlike traditional silver or aluminum mirrors that break under high temperatures, temperable mirrors can be cut, CNC drilled, and physically tempered. This provides superior safety, high impact strength, and excellent weather resistance for outdoor and architectural applications.
Are you a trading company or a direct temperable mirror glass factory in China?
We are a direct, leading temperable mirror glass factory and supplier based in China. Operating under our official brand North One Glass, we run the largest vacuum magnetron sputtering coating line domestically. This allows us to provide a stable bulk supply and offer the most competitive factory wholesale prices directly to global B2B buyers.
Why should glass processing plants choose temperable mirrors over traditional mirrors?
Traditional mirrors cannot be tempered to meet modern building safety codes, and they easily oxidize, peel, or develop black edges when exposed to moisture or outdoor air. Our temperable mirror solves all these issues—it can be fully toughened, possesses a hard, durable coating, and carries a 20-year outdoor warranty without any degradation.
Will the mirror coating color change after the high-temperature tempering process?
No, absolutely not. One of North One Glass's core technical advantages is that there is zero color difference (no LAB value change) before and after the physical thermal tempering process. The reflection color remains a premium, neutral, colorless tone, ensuring visual consistency across large building facades.
How many years can your temperable mirror glass last in outdoor environments?
Our temperable mirror offers 20 years of outdoor durability. The advanced offline magnetron sputtering film layer is highly resistant to oxidation, acids, and alkalis. It will not peel, discolor, or develop black edges even when exposed to harsh outdoor weather, rain, sunshine, or coastal salt fog.
What are the standard optical parameters of your temperable mirror?
Our standard stock temperable mirror features a visible light transmittance (VLT) of 5% and a reflectance of 75% on the film side, yielding an ultra-bright reflection. However, as a custom manufacturer, we can adjust the transmittance from 25% down to 0% to fit your exact project specifications.
What thicknesses of temperable coated glass do you supply for bulk purchase?
We offer a comprehensive thickness selection to support various industrial applications: 1.1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 8mm, 10mm, 12mm, and 15mm. Thicker sheets are widely used for structural curtain walls, while thinner options are perfect for high-end decor and framing.
What is the maximum jumbo size of temperable mirror glass you can manufacture?
Our standard stock sizes range from 915*1220mm to 3300*4880mm. For grand architectural designs, North One Glass can manufacture incredible jumbo sizes up to 3300mm × 16000mm, which is an elite capability in the global glass sourcing market.
How does your product help local glass factories improve their yield rate and cut costs?
Our hard-coated film is extremely durable and chemically stable. When local glass processing plants perform secondary operations like cutting, edge grinding, shape profiling, and CNC drilling, the coating edge will not chip or peel. This ensures a significantly higher final tempering yield rate, maximizing your utilization rate and reducing material waste.
How much does temperable mirror glass cost from a China manufacturer?
The price (how much it costs) varies depending on the glass thickness, sheet size, order volume, and shipping requirements. Because we are a direct source factory, we guarantee the best tiered wholesale prices for large-volume distributors. Please contact our sales team to get an accurate quote based on your specific sourcing requirements.
Has your temperable mirror glass coating passed any durability or scratch-resistance tests?
Yes. Our mirror glass coating has passed the rigorous 5,000-cycle steel wool scratch test without any peeling, flaking, or scratching. It also passes demanding acid, alkali, and salt spray testing, proving it is completely safe for high-end bathrooms, coastal projects, and harsh outdoor scenery.
Can we buy large raw sheets from you, or do you only supply finished mirror products?
We offer both options for international sourcing. We can supply large raw sheets (offline coated sheets) for overseas glass processors to cut and temper locally. Alternatively, we can handle the entire fabrication process in-house and ship fully customized, pre-cut, CNC-ground, and tempered finished mirrors directly to your job site.
What are the main B2B target applications for temperable mirror glass?
Our temperable mirrors are highly sought after by commercial architectural curtain wall contractors, indoor and outdoor high-end decoration firms, luxury outdoor landscape designers, and premium mirror manufacturing plants requiring high-strength, weather-resistant safety mirrors.
How does North One Glass prevent breakage during international ocean freight shipping?
In-transit breakage is a primary concern for bulk buyers. We package all orders using heavy-duty, seaworthy export wooden crates or sturdy A-frames, with protective paper or powder interleaved between every single sheet of glass. Every container is securely braced and tied down to withstand long maritime voyages.
What is your Minimum Order Quantity (MOQ) for a custom size temperable mirror order?
For our standard stock sizes and regular thicknesses, the MOQ is highly flexible (usually 1 full crate). For non-standard thicknesses or custom optical performance parameters, the MOQ depends on our coating line run schedule. Please message our support team to discuss low-MOQ sourcing options.
Why should we choose North One Glass as our long-term temperable mirror supplier?
North One Glass stands out because of our massive production capacity, strict quality control (deionized pure water washing, premium float glass selection), zero-color-change tempering technology, and unmatched jumbo size capabilities. We focus on helping global B2B clients maximize their yield rates and achieve long-term project durability.
