Getting vertical picket infill components right the first time saves contractors serious headaches and project delays. After 23 years in stainless steel railing manufacturing, we’ve seen every spacing nightmare, code compliance mess, and installation challenge you can imagine. The difference between a smooth project and a costly redesign often comes down to choosing components that actually work together as a system—not just individual parts that look good on paper.
Complete Vertical Picket Infill Systems
Modular Component Architecture
Our vertical picket infill components integrate seamlessly across residential and commercial applications. The system includes precision-manufactured pickets in 304 and 316L stainless steel, compatible mounting hardware, adjustable spacing systems, and code-compliant connection methods.
Standard Picket Specifications:
- Diameters: 12mm, 16mm, 20mm solid rod options
- Heights: Cut to specification or standard 36″, 42″, 48″ lengths
- Spacing: Adjustable system maintains 4″ maximum sphere compliance
- Connections: Top and bottom rail integration with secure mechanical fastening
Material Selection for Performance:
- 304 Stainless: Interior applications, standard atmospheric exposure, cost-effective for most commercial projects
- 316L Marine Grade: Coastal environments, chemical exposure, pool areas, industrial applications requiring maximum corrosion resistance
- Surface Options: Brushed finish for durability, mirror polish for architectural applications
Precision Manufacturing Advantages
Vertical picket fabrication 316L processes ensure consistent dimensional accuracy across production runs. Our CNC machining maintains ±0.5mm tolerance on critical dimensions, eliminating field adjustment issues that slow installations.
Modular design means contractors can stock standard components while still handling custom spacing requirements. Pre-fabricated mounting brackets reduce field assembly time by approximately 35% compared to welded-in-place systems.

Frequently Asked Questions
Q: How do I choose between 304 and 316L stainless for vertical picket applications?
A: 304 stainless works well for interior and standard exterior applications with normal atmospheric exposure. Choose 316L for coastal environments (within 5 miles of saltwater), pool areas, industrial chemical exposure, or where 30+ year service life is required. The material cost difference is typically 25-35%, but maintenance savings justify 316L in harsh environments.
Q: What spacing options maintain code compliance for the 4-inch sphere test?
A: Our adjustable mounting system accommodates spacing from 3″ to 3.9″ on center, providing compliance margin while allowing architectural flexibility. Precision picket infill components include verification guides ensuring consistent spacing during installation.
Q: How do modular systems compare to custom fabrication for project timelines?
A: Modular components typically reduce installation time 35-40% compared to field-welded systems. Pre-fabricated mounting brackets eliminate most field adjustment, and standard components ship faster than custom fabrications. For projects over 100 linear feet, the time savings usually offset any premium for modular design.
Q: What maintenance is required for vertical picket infill systems?
A: Annual inspection checking connection tightness and cleaning with mild detergent maintains appearance and performance. 304 stainless may require more frequent cleaning in industrial environments. 316L systems in marine applications typically need only bi-annual maintenance. Our 23 years of experience shows proper material selection reduces maintenance costs significantly.
Q: Can your components integrate with existing railing systems?
A: Yes, our modular design accommodates most standard top and bottom rail configurations. We provide custom mounting hardware for integration with existing posts and rails. Engineering review ensures proper load transfer and code compliance when retrofitting existing systems.
Q: What lead times should contractors expect for different order quantities?
A: Standard components (under 500 linear feet): 2-3 weeks. Large projects (500+ linear feet): 4-6 weeks. Custom picket manufacturing with specialized dimensions: 6-8 weeks. We coordinate delivery schedules with project timelines and provide progress updates throughout manufacturing.
