About the company

Grimco manufactures and distributes materials and equipment for businesses that make signs, vehicle graphics and printed displays. Its catalog spans adhesive films and rigid panels as well as printers, inks and lighting components, so customers can source production equipment and the materials it consumes from one supplier. The company sells these products through local branches and an online store, where business accounts can check prices, product availability and delivery estimates before placing orders. Founded in 1875 in St. Louis, Grimco is a privately held, family-owned business headquartered in Sunset Hills, Missouri, with operations in the United States, Canada and the United Kingdom.

Simplify's Take

What believers are saying

  • Fenton sales hires have paid orientation opportunities: Grimco includes shadowing and travel expenses under its travel policy.
  • Kennesaw warehouse staff get low-cost coverage: employee-only medical premiums cost $16.50 per biweekly paycheck.
  • US careers list company-paid protection: Grimco includes life insurance plus short-term and long-term disability coverage.

What critics are saying

  • Kennesaw warehouse work demands heavy handling: Grimco requires frequently moving materials weighing 70 pounds or more.
  • Sunset Hills recruiter applicants face a visa limit: Grimco excludes present and future sponsorship for this position.
  • Large shipments add customer costs: Grimco charges at least $175 for every motor freight shipment.

What makes Grimco unique

  • Grimco stocks exclusive labels: Briteline, HanleyLED and MAXMETAL sit alongside third-party sign supplies.
  • Grimco protects customer relationships: wholesale accounts require sign-making equipment, keeping end users from buying directly.
  • Grimco handles regulated signage: its 3M-approved production process meets transportation department standards for finished traffic signs.
