Our Tradition is Putting the Customer First

We’ve been helping businesses procure supplies better since 1930 and our procurement and distribution systems have grown to include:

2000+ manufacturers

6000+ customers

Our small town retail hardware store roots taught us to treat every customer as our most important. 90 years since that tiny hardware store opened, you could say we still feel the same way about our customers.

We've grown from selling single pieces of hardware to being an integral part of our corporate clients' operations -- supplying them with a massive inventory of options and innovative procurement methods that save time and money. We've tailored the process to meet the needs of our clients, offering convenient online and phone ordering options, EDI, and purchasing platforms along with our industry-leading in-plant storerooms and on-site dispensing machines.

We like to say that every customer call, no matter how small, is answered efficiently by a real person.

We pride ourselves on offering guidance to businesses — suggesting the best product solutions, helping you create a better supply chain -- we’re ready to help you get the job done.

Quality & Timely Service

Our Tiemann team is dedicated to supplying your business with what it needs to grow. We believe our future rests in getting the job done right the first time and with 90 years experience, we’re planning to keep on growing.
