SONNE was born because our founders have trouble in finding good options for aluminium door and window that worths the values. Hence this is the personal tips from our founder when finding trusted aluminium door & window suppliers:
- Check their factory situation: the size of factory, the machines used, and the quality control process. Ask for their pictures. SONNE follows a very rigorous process of production and test fulfilling ISO 9001 standard and the standard to enter US, EU, AU, SA, China market. Automatic machine will improve precision of cutting and glassmaking machines.
- Go to their showroom and check the quality of their products. See here for the tips on how to check product quality and please visit our 100sqm showroom in Bekasi
- Evaluate how transparent their sales team in sharing the information. Double check their catalogue and whether the information is detailed for you to make the decision. Choose only those that you can trust to give you real knowledge.
- Do not judge solely because of price, project, or third-party references. Every detail matters, it is important that you ask as detailed as possible and double check the information to the supplier directly even with the information you get from third party.
