The Inland Empire is the largest warehouse and distribution market in America. Square miles of new membrane roof, every acre of it dotted with units, hatches, and skylights. Around it sits the food-processing belt from the Chino dairy basin to the bottling lines, the ports, and the specialty-chemical blenders we already serve. All of it answers to Cal/OSHA. A genuinely different rulebook, and our guardrail line’s parapet base is named for the exact section that governs it.
Cal/OSHA’s Title 8 has its own sections and specifics. Guardrail criteria live in §3209, and California carries its own rules on skylights and roof work. Interpretation is always the inspector’s, here like anywhere. Our part is making sure the paperwork speaks the state’s language: every California read we write cites Title 8 sections alongside the federal ones, and the Cal-specific base system exists in our guardrail line for exactly that reason.
The work here tilts hard to platforms and rooftops: mezzanine and conveyor access inside the DCs, non-penetrating guardrail and hatch/skylight protection across the IE’s roof acreage, and food-grade access in the processing belt. Stainless and aluminum where washdown eats galvanized.

The biggest DC market in the country. Perimeter guardrail, hatch guards, and skylight screens, all non-penetrating on new membranes.
The Chino basin dairies, bottling, and food plants. Washdown-grade access, receiving bays, and the up-top tasks bottom-loading doesn’t erase.
Solvent, coatings, and adhesive blenders from the IE to the harbor. Our mid-market chemical playbook: drum-to-bulk transitions, venting and sampling access, right-sized to one-to-six spots.

California enforces its own Title 8 rather than federal 29 CFR 1910. Guardrail criteria live in §3209, and the state carries its own skylight and roof-work rules with their own enforcement history. Our California reads cite Title 8 alongside the federal standards, and our guardrail line includes a parapet base system engineered specifically to §3209.
Yes. That’s the flagship: freestanding, counterweighted guardrail that stands on the membrane with no drilling, no flashing, and no warranty argument with your roofer, plus non-penetrating hatch and skylight protection to match.
Rooftop fall protection across the distribution buildings, modular platforms and crossovers inside them, food-grade access in the processing belt, and loading access at the blenders. Sized by a walk, quoted with the drawing.
