Saf-T-Box has been in the container manufacturing, modification, rental, and sales business for over 20 years. We repurpose International Standards Organization (ISO) shipping containers, made for cargo transport on ocean freighters, into storage units, office spaces, and much more. These strong, secure, weatherproof containers come in a variety of sizes and are available for purchase or rent. We have five Texas offices in Longview, Beaumont, Houston, San Antonio and Austin.
