I want to express my "great gratitude" to the NGO Stroyprofil G. Borisov for the professionalism and culture of communication with the buyer, after the conclusion of the contract.This company could not correctly calculate the number of membranes for the roof of 146 sq.m., for some reason it took 3 rolls of 80 sq.m., and the number of the most profiled metal tiles.After that, they rudely explained to us that they had calculated everything correctly, but our employees simply did not cover our roof correctly.But that's not the task, the roof is covered all over and the pattern matches everywhere, and there are 20 sheets left.I do not recommend this company, because in the beginning everyone is friendly and courteous, but after drawing up the contract they talk in raised tones.(Even just a question about the production time of the material causes the seller a storm of emotions and an answer:"How do I know!!!")
