Russian to English Bus/Financial Marketing / Market Research

There is a term "сегмент по направлению" that I came across in the "Product Specifications" section of the company's business plan. The context is market research (market segment analysis).

The complete sentence is: "По мнению участников строительного рынка, во многих сегментах по направлению "строительные материалы" имеется существенный дефицит."

My variant: "According to players of the construction market, many market segments directed toward the construction materials sector experience sginificant deficit".

Can this term be translated as "the market segment directed toward" given the current context, or would there be a better variant?

Thank you in advance for your help!
