Our Motto is Customer Satisfaction

We engineer our systems with the customer in mind. Our goals are simple:

  • The design of our products to meet all of our customers’ requirements.

  • Our products are engineered, built and tested to meet all of the Rules set forth by the Regulatory Agency governing the project.

  • We use the best materials for longevity of our systems.

  • We use components that are readily available and will remain readily available for many years. This is accomplished by using commercial products from U.S. Companies who have been in business for at least 30 years. The most up to date components, but not ones that require specialists to maintain or troubleshoot are provided.

  • We design our products so special tools are NOT required. You can completely assemble and disassemble the whole system with standard hand tools. The designs prioritize the accessibility of all components.

  • Our systems are designed to keep Installation time and costs to an absolute minimum along with meeting the customer’s installation constraints.

  • All equipment will have lifting eyes in place for safe and easy handling.

  • Most importantly, we design & engineer for lean manufacturing. This keeps our costs and overhead to a minimum so that we can reflect the savings to our customers with budget prices.
