What Blockader does

Blockader is a division of Tamis Corporation, headquartered in Monroeville, Pennsylvania, and has manufactured galvanized interlocking steel crowd control barriers since 1976 under the Blockader® brand. The company's core products are hot-dip galvanized steel barricades built with a proprietary 3-way hooking system, true 16-gauge steel frames and bases, and saddle-cut welds with fully-inserted uprights rather than spot welds. Bolt-on replaceable bases (bridge, flat, U-base, and wheel), a 40-year claimed corrosion life, and interoperability with existing barrier inventories form the technical foundation of the product line. The portfolio extends beyond steel into plastic pedestrian barricades (LineEx, Movit), aluminum stage barriers, welded-wire temporary fencing (Perimeter Patrol, SmartWeld), scissor/accordion security gates, stanchions, and signage accessories, organized across multiple sub-brands and seven wholly-owned micro-sites.

Blockader operates a multi-channel go-to-market combining direct phone sales (800-448-2647), an e-commerce website with quote-cart functionality, a dealer login portal, and a national rental partnership with ALLY Rental, which alone maintains over 12,000 barricades in active use plus 8,000 backup units across North America. Revenue is generated primarily through hardware sales of steel barriers, plastic barriers, gates, fencing, accessories, and replacement parts, with unit pricing in the $59–$82 range for KROMA-branded SKUs and volume discounts available for larger orders. Customization services — powder coating in 8+ colors, laser-cut signage, reflective sheeting, branded barrier jackets, and special-order frame variations — represent a meaningful adjacent revenue stream. The customer base spans event venues (Super Bowl, Olympics, Presidential Inaugurations, Las Vegas Convention Center), government and law enforcement (Boston Police, UN Visitor Centre, NYC DOT), entertainment (Disney), destination management firms, construction sites, hospitality, and rental companies, with no single end customer appearing to dominate.
