    For three decades, Clark Welding Service has provided products within the storage tank industry. We are familiar with the standards and publications of the Underwriters Laboratories (UL) and the Steel Tank Institute (STI). To help our customers comply with code enforcements of fire marshals, such as NFPA30, and requirements, such as 40 CFR 112, we can provide products designed to specific standards with labeling, such as UL-142, UL-2085 and Flameshield. We assist customers in planning and estimating the costs of their project by reviewing the scope specified from their organization, their engineers or their authorities handling jurisdiction. Alternatively, we can provide a quote for a typical application for our customer to submit to their authority handling jurisdiction for review. We can consult with customers regarding specific issues, such as space restrictions, to ensure that we provide the most suitable product.
