Section 1 – Conflict Minerals Disclosure

Items 1.01 and 1.02 Conflict Minerals Disclosure and Report, Exhibit

Gibraltar Industries, Inc. (“Gibraltar” or the “Company”) has evaluated its current product lines and determined that certain products that the Company manufactures or contracts to manufacture contain tin, tungsten, tantalum, or gold, which are necessary to the functionality or production of the Company’s products into which these minerals have been incorporated. Rule 13p-1 and Form SD established under the Securities Exchange Act of 1934 define these minerals as “Conflict Minerals” and, as a result, the Company is required to conduct in good faith, a reasonable country of origin inquiry that is reasonably designed to determine whether any of the conflict minerals originated in the Democratic Republic of Congo or an adjoining country or are from recycled or scrap sources. Accordingly, Gibraltar is filing this disclosure, along with a Conflict Minerals Report referred to below.

Conflict Minerals Disclosure

The Company has engaged and is continuing to engage in a due diligence process, including surveying the Company's direct suppliers via an industry-standard based survey template for conflict minerals, to try to determine the sources of the conflict minerals used in the Company's products and which are purchased through a complex supply chain.

Based on the Company's due diligence efforts and the surveys received from the Company's direct suppliers, the Company concluded that a portion of its necessary Conflict Minerals originated in the covered countries and such necessary Conflict Minerals may not have been from recycled or scrap sources.

The Conflict Minerals Report required by Item 1.01 of Form SD is filed as Exhibit 1.01 hereto and is publicly available at www.gibraltar1.com under the heading “Investors” and the sub-heading “Financial Analysis & SEC Filings.”
