Link building for manufacturing business... Tips?

[RayflexGroup]

What are your tips for B2B link building? We manufacture and supply PVC strip curtains & rubber site safety products but currently lacking creativity for link building ideas.  
Does anybody have any case studies or tips to help us out?

Looks like you have been in business since 1975.  You probably know enough about these products to "write the Bible" on them.   You are the experts.  Start writing about what people ask about them and what they don't ask that they should be asking.

Agree with EGOL above. Blogging and creating helpful content that people visiting your website would like to read is a great strategy. You could also see if any businesses that you buy from or that buy from you have a "Resources" or "Partners" section on their website and request to be added to it if it makes sense. Making sure your listed on credible online business directories like Yelp, Angieslist, BBB, Manta, YP, etc wouldn't hurt either, even if you ship nationwide.

Once you have blog posts and content written, you can Google "manufacturing blogs" or "manufacturing company lists" or "manufacturing forums" and see if they are credible websites, see if you can participate in them, request to be listed, or start to build relationships with the website owners to see if you can send over your blog posts/content to see if it can be featured.
