Cantilever · Lattice · Louvered · Solid
The 4K lattice system is the workhorse of aluminum patio covers — clean sight lines, reliable shade, and the kind of timeless look that complements any home style. Available in 2" and 3" profiles to match your aesthetic and functional needs.
All 4K systems are engineered to California building code, including wind and seismic loads, and come permit-ready. We handle the full scope — from design through final city inspection.
The finer, more elegant profile. The 2" lattice creates a refined grid pattern with more shade coverage and a sophisticated visual density — perfect for traditional and transitional home styles.
Bolder spacing with a more open, airy feel. The 3" profile lets more light through and suits modern and contemporary homes. Great for those who want shade without closing off the sky.
A clean, post-free front edge. Cantilever framing carries the cover from the back, leaving the front fully open — no posts to block the view or your walkway. The modern choice for decks, entries, and poolside patios.
Choose the lattice density that works for your home's style. Both profiles use the same heavy-wall extrusions for structural integrity.
Designed to attach to your home's ledger board or stand independently as a pergola-style structure with our heavy-duty post systems.
Every 4K job comes with full engineering documentation for the city permit process. We manage it so you don't have to.
30+ powder coat colors available. Durable, UV-resistant finish that won't fade, chip, or peel in Southern California's climate.
Add LED strip lighting, pendant lights, ceiling fans, or patio heaters to your 4K cover. All electrical work is code-compliant and permitted.
Unlike wood pergolas, aluminum never rots, splits, warps, or needs painting. Wash it down once a year and it looks new indefinitely.
