System Advantages Overview
Clear Space for Cars

Obstruction-Free: Column anchors mount at the parking stall boundary line.

Driver Convenience: Zero front posts allow drivers to open doors fully and reverse safely without collision risks.

Cantilever Strength

High Load Capacity: Rated for asymmetrical wind uplift speeds up to 50 m/s.

Robust Structure: Hot-dip galvanized H-shaped steel columns and beams absorb high bending moments at knee joints.

Long-Term Stability: Heavy-duty bolted connections withstand years of cyclic environmental loading.

Fewer Footings

Reduced Foundations: A single-spine design requires only one foundation per bay, minimizing required cast-in-place footings or drilled piles per megawatt.

Faster Deployment: Decreased earthwork accelerates concrete curing and allows the parking lot to return to service sooner.

Adjustable Geometry & Clearance

Flexible Tilt: Array angles adjust between 5�° and 15�° to meet site-specific energy requirements.

Versatile Clearance: Standard clearance is set at 2.2 m for passenger cars, with scalable options up to 4.0 m+ for commercial fleets.

Broad Compatibility: Cross beams and W-gutter rails support both standard framed and glass-glass bifacial modules using pre-assembled end and inter clamp kits.

Testing & Certifications

Safety & Compliance: Certified under UL 2703 (Bonding, Grounding, Mechanical Load), CE mark, and MCS.

Structural Ratings: Complies with AS/NZS 1170 and Eurocode standards for severe wind and snow loads.

Corrosion Resistance: Salt spray tested for anodized aluminum and stainless steel components.

System Advantages Overview

Structural Rigidity & Durability

Materials: AL6005-T5 anodized aluminum framing paired with Q355B hot-dip galvanized steel bases.
Corrosion Resistance: Zinc-coated steel withstands harsh coastal moisture and winter road salt.
Load Bearing: Primary beams and purlins effectively support array loads across wide bays to maintain maximum structural rigidity.

Water Management

Watertight Design: Utilizes micro-gutter rails and EPDM gaskets at module seams to capture rainwater, creating a dry parking area without the cost of a secondary steel roof.
Drainage: Water is safely routed to grade via external downspouts attached along the rear columns.

Simplified Field Assembly

Pre-assembly: Main structural nodes and bents are assembled at the factory to save time.
Installation: On-site crews simply set the columns, lift the upper framework, and lock the system together using highly durable SUS304 stainless steel fasteners.

Concealed Wire Routing

Protection: PV string wiring and EV charging conduits are routed inside the internal cavities of beams and posts, shielding them from UV degradation and vandalism.
Aesthetics: Eliminates exposed wire bundles, resulting in a clean, high-end architectural profile.

Testing & Certifications

Standards: CE mark, MCS certification, and UL 2703 (Bonding, Grounding, and Mechanical Load).
Environmental Loads: Fully compliant with AS/NZS 1170 and Eurocode for severe wind and snow loads.
Durability Testing: Rigorous salt spray testing completed for anodized aluminum and stainless fasteners.

Quality Assurance

Backed by a comprehensive 10-year product quality warranty.

Material & Structural Specifications
Rails are extruded from anodized aluminum or roll-formed from hot-dip galvanized carbon steel (Q235B/Q355). 304 stainless steel fasteners break the galvanic corrosion cycle wherever dissimilar metals meet. Our engineering team runs site-specific wind and snow load calculations during the design phase to verify the layout meets your local structural codes.

Mounting Solutions by Roof Type and Profile
Metal Roofs: Standing Seam and Trapezoidal
Our non-penetrating clamps grip the standing seam directly â?? no holes in the roof, no leak paths, and the factory warranty stays intact. For exposed-fastened trapezoidal profiles, short-rail kits use hanger bolts backed by EPDM washers to seal out moisture at each attachment point.

Residential Tile
Our height-adjustable roof hooks fit S-tile, flat concrete, and clay roofs. The base plates dial in the level to compensate for uneven roof planes and inconsistent batten spacing. The hook bolts through the sheathing into the rafter, clearing the tile completely. Dead load and wind forces follow a clean load path: module to rail to hook to rafter.

Flat Commercial Decks
Concrete, TPO, and EPDM membranes take either ballasted or mechanically anchored setups. No roof penetrations on ballasted layouts â?? the array stays in place under its own weight. You set the tilt angle between 5° and 30° based on your site's target yield and wind zone. Older buildings often have tight structural limits. Adding rear wind deflectors to a ballasted layout mitigates aerodynamic uplift. Less uplift drops the required ballast weight, keeping the total rooftop dead load (psf) inside acceptable structural margins.

Rooftop Racking for Commercial & Residential Solar
Racking systems for flat, tile, and metal roofs. We size each mounting setup to your structural limits so nothing moves once it's up.

AL6005-T5 & SUS304
Anodized AL6005-T5 aluminum and 300-series stainless steel won't corrode or degrade on the roof, even after decades of exposure.
Pre-Assembled Parts
Clamps and foldable tilt legs ship assembled. Click-in nuts drop into the rails, cutting loose hardware and install time on site.
Wind & Snow Ratings
We size rail spans and support spacing from your site data. The extrusions handle heavy snowpack and wind uplift without deforming.
Large Panel Fit
Clamps fit 30â??40mm module frames. Rail spacing adapts to high-wattage, large-format panels across varying tilts and layouts.
Roof Seal Integrity
Seam clamps grip the metal without drilling. Where hanger bolts penetrate the deck, EPDM washers compress to seal the opening.
Tested & Certified
Hardware meets AS/NZS 1170, CE, and UL 2703. Pull-out tests and salt spray cycles confirm load capacity and corrosion resistance.

Brief instruction:flexible metal hose assemblies are a wonderful alternative to hard line steel or stainless steel tube assemblies where greater flexibility is needed.Because flexible metal hose assemblies are stainless steel throughout, they meet the need for chemical and extreme temperature resistance. The corrugated core tube allows flexibility that a hard line cannot.� //
A corrugated stainless steel hose with external stainless braiding. It is commonly used in high temperature or highly corrosive applications where a rubber hose is not suitable. It is also popular in "permanent" piping installations and short lengths (jumper) in potable water, cooling, steam, or other liquid applications where a "rubber hose" does not provide enough flexibility or a long enough service life (ie. Rubber and plastics will degrade when subject to the elements). The braiding acts as a reinforcement to increase pressure ratings and prevent elongation.//
There are many different types of end connections available for flexible metal hose assemblies:
