Our Materials

At Klein Steel, when we boast about our complete array of in-stock materials, we define “complete” to mean exhaustive. With over 3,500 lines of inventory in our state-of-the-art Kasto inventory management system, we have what you need: carbon, stainless and aluminum; plates, sheets, bars, tubes, and more (see line card below). We also have a willingness to add new stock items at any time. Seeking something unusual that we don't typically keep in stock? Let us know. We're more than happy to work with you to ensure we always have available the materials that you need—when you need them.

Our ability to thrive and grow in a very competitive industry is based not just on living our core values, but also on our agility to meet shifting customer needs and emerging opportunities. However, what's even better than the Klein Steel rapid response is our ability to work with you, our valued customers, using your specific purchase history and production forecast, to meet your needs proactively. If product availability is one of your critical needs, we're the partner for you.

Whether you have a commercial application or are seeking nuclear commercial-grade dedication materials, Klein Steel can help. We are NQA-1 compliant and can offer you ASME nuclear safety materials.
