Heat Treated Glass

What is 4mm Toughened Glass Panel?
Our 4mm toughened glass panel is a premium tempered safety glass designed for durability, impact resistance, and thermal stability. Processed through a controlled heat treatment, it is up to five times stronger than standard float glass and breaks safely into small, blunt fragments upon impact, reducing the risk of injury.
Ideal for windows, doors, partitions, shower screens, and other interior or exterior applications, this 4mm tempered glass offers the perfect balance between strength and aesthetics. It complies with international safety standards and is widely used in residential, commercial, and architectural glazing projects.

FAQs for Order 4mm Tempered Safety Glass
For a first-time cooperation, we are happy to provide free samples for simple products such as clear tempered glass and clear laminated glass to support our initial collaboration. However, we are unable to cover the shipping costs. We hope both sides can share some of the expenses from a partnership perspective. If this order and project move forward and we work together in the future, these costs can be fully deducted from our formal cooperation.
In general, this is not a problem. Please contact us using the form below, and our team will get in touch with you.
Additionally, please note that our partner suppliers are located in various regions across China, and the glass and aluminum factories in particular are often situated in relatively remote areas. Visiting them in person can be costly overall. If you would like to save time and effort, we can arrange to visit them on your behalf under your company’s name.
Yes, we do offer door-to-door service. We can arrange it according to your location, and the exact cost and lead time will be confirmed based on the destination and shipping method you prefer.
The shipping cost depends on the destination, product type, and shipping method (air, sea, or express).
For large or heavy items like glass, window, door, curtain wall, sea freight is usually the most cost-effective option. While international shipping can be a significant part of the total cost, we always work to find the most economical and efficient solution for our customers and can provide a detailed quotation for your reference.
For tempered glass and standard laminated glass, we generally offer a 5-year warranty. For higher-performance glass, such as insulated glass, Low-E glass, and coated glass, we typically provide a 10-year warranty.
Please note: As glass is inherently fragile, there is always a risk of breakage during transportation. Even for tempered glass, despite our use of high-quality raw glass from XYG, CSG, and PPG, and processing with advanced tempering furnaces from NorthGlass and LandGlass, there is still an approximate 0.2% risk of spontaneous breakage. If any damage occurs, we will do our best to assist you in minimizing the loss.
Of course. Xpert BM was founded with the mission of helping all our clients solve their challenges. Our primary customers are individuals small and medium contractors, and we are always happy to listen to their ideas. Our professional team will carefully consider their needs and provide the most suitable advice and recommendations.
