Hello Sir / Madam,
My name is Suna from China, I'm working in GALUMINIUM GROUP which exports Aluminium Windows and Doors and Aluminium Profiles.
About the shape, color or size of the products can be custom-tailored to suit your own requirements. The price of the products depends on what you want.
For the profiles, the price is different depending on the surface treatment you want. Normally, it ranges from 2650 USD dollars to 5000 USD dollars with FOB price. The minimum order should be 1 metric ton (1000kg).
For the windows and doors, the price depends on the size and the types you want (with louver or not, with glass or not, casement or bi-folding or sliding ones). Would you mind send me the pictures of those windows or doors you want and tell me your requirements on the products, so I can estimate the price list for you and produce products upon your need.
For the curtain wall, we can offer you the price by square meter but it also depends on what kinds of glasses you want. Without your detailed requirements, it's impossible to give you a reasonable price.
The attachments are the catalogue of my company and my name card. If you want more details, please feel free to contact me.
