Welna-Andrén Sweden
Sales and customer contact
Swedish family-owned company in Gothenburg. This is where the conversation about glass-fibre equipment starts: we take your enquiry, work out the technical requirements with you and coordinate design and manufacturing in Latvia. Going forward we will also sell Valtank steel tanks.
