I am looking for aluminum sliding profiles, and I have attached a few photos showing exactly what I am looking for. Could you please let me know what the price would be per 1 kg of the product?

Our company deals with the sale and installation of aluminum constructions (patio roofs and related products). Due to the expansion of our activities, we are considering cooperating with your factory. We would like to know the following: Is it possible to supply aluminum profiles and products in the color we desire? Do you manufacture parts according to our specific dimensions and drawings?
