What Rock Products does

Rock Products is a B2B trade media company serving the aggregates (sand, gravel, crushed stone) and construction materials industry, operated by Denver-based SEMCO Publishing, LLC. Founded in 1896, it is the longest-running publication in the aggregates vertical, reaching quarry executives, production managers, maintenance personnel, market analysts, and mining engineering students across North America (USA, Canada, Mexico). The publication's core offerings include a monthly print magazine, the rockproducts.com website with over a decade of archived content, and three e-newsletters (Breaking Rock News, The Rock Report, Prime-Time Products). Editorial coverage spans aggregates-processing equipment (drilling, blasting, crushing, screening, conveying, hauling), operational efficiency, management best practices, market analysis, and emerging trends including sustainability and automation.

The business is monetized through three primary revenue streams: recurring print and digital subscriptions, advertising sold to equipment OEMs and service providers, and e-newsletter sponsorships. The company has expanded beyond the legacy print+digital model into a broader SEMCO Publishing portfolio that includes ROCKtv (video content), LeadLink (lead-generation platform), AggNexus (annual Digital Innovation Conference), Aggregates Atlas (industry directory), The Pulse / AVP Pulse Index (quarterly market sentiment index in partnership with Allen-Villere Partners), and sub-brands such as Prime-Time Products and Rock Stars. Sister publications under SEMCO include Cement Optimized, The ASIA Miner, and North American Mining. The company is privately held, has 11-50 employees, and has had Mark S. Kuhar as editor since 2010. No public ownership, institutional investment, or PE involvement is indicated.
