Explore our flagship aluminum alloy L-Feet mounting kits customized for industrial tin and corrugated metal rooftops. Built with sub-zero resilient EPDM seals and high tensile strength for northern steppe climates.
Erdenet, the capital of Orkhon Province and the second-largest city in Mongolia, represents one of Asia's most vital industrial mining epicenters. Home to massive copper and molybdenum processing operations, including the Erdenet Mining Corporation, the region's urban and industrial layout is dominated by heavy manufacturing infrastructure, sprawling warehouse complexes, logistics facilities, and municipal tin-roof buildings. As Mongolia aggressively pursues energy independence, decarbonization, and grid stabilization through renewable energy adoption, commercial solar photovoltaic (PV) retrofitting across tin and trapezoidal metal roofs in Erdenet has experienced exponential growth.
However, designing and deploying solar PV mounting hardware in Erdenet demands engineering rigor far exceeding standard temperate-zone specifications. The micro-climate of Northern Mongolia presents severe structural and environmental stress vectors:
Erdenet features extreme continental sub-zero winter temperatures dipping below -40°C. Standard plastic washers and poor-grade rubber gaskets freeze, embrittle, and shatter, leading to roof leakage. Our L-Feet kits use specialized UV-resistant, low-temperature EPDM rubber seals retaining full elasticity from -50°C to +120°C.
Heavy snowfall accumulation across Orkhon Province imposes mechanical downward pressures up to 2.4 kN/m². Solar mounting L-feet must transfer heavy structural loads directly into roof purlins or structural rafters without deforming trapezoidal steel sheets.
Open mountain-steppe terrain generates intense lateral wind gusts reaching 42 m/s. Precision-engineered AL6005-T5 structural aluminum combined with M8 SUS304 stainless fasteners ensures high pull-out resistance against roof fatigue.
The L-Foot bracket is the critical interface link in rooftop solar mounting systems, securing solar rails to the building structure while keeping the metal sheet envelope watertight. In cold-climate industrial centers like Erdenet, selecting the appropriate structural alloy, fastener grade, and sealing geometry determines whether a solar installation survives a 25-year operational lifecycle.
Xiamen Illumino Solar manufactures all tin roof L-Feet using high-grade extruded aluminum alloy AL6005-T5. T5 heat-treatment aging provides optimized tensile yield strength (≥ 240 MPa) and ultimate tensile strength (≥ 260 MPa), outperforming basic AL6063-T5 components commonly used in low-cost alternatives.
To prevent galvanizing reaction and corrosion caused by industrial particulate matter in copper mining districts, our components undergo anodization treatment exceeding 12μm thickness (Anodized Class AA15 upon request). This layer acts as an electrical insulator and chemical barrier against acid rain, sulfur particulates, and harsh environmental wear.
Direct roof penetration carries inherent water leakage risks if unmanaged. Our L-Feet kits feature integrated, heavy-duty EPDM (Ethylene Propylene Diene Monomer) vulcanized rubber pads and bonded steel/EPDM sealing washers.
Under torque pressure from self-drilling M6.3/M8 wood/metal fasteners, the pre-grooved EPDM base pads compress uniformly into trapezoidal or corrugated metal profiles. The mechanical geometry prevents water pooling around penetration holes even during violent spring snowmelt cycles in Northern Mongolia.

International Engineering, Procurement, and Construction (EPC) companies, as well as institutional developers managing energy retrofits in East Asia and Central Asia, require absolute compliance with internationally recognized structural and environmental standards. Procuring uncertified solar mounting components creates severe project liability, premature fatigue failures, and expensive roof repairs.
Our L-Feet solar mounting kits are structural-engineering verified in accordance with AS/NZS 1170.2 (Wind Actions) and Eurocode 1 (EN 1991-1-4). Finite Element Analysis (FEA) simulations verify force distribution, shear torque resilience, and pull-out safety factors across thin sheet tin roofs.

Metal tin rooftops across Erdenet exhibit varied profiles—ranging from standard trapezoidal corrugated metal sheets to standing seam panels and heavy industrial steel corrugated decks. Solar mounting systems must provide versatile adaptability to integrate cleanly with local architectural and structural profiles.
Heavy industrial workshops in Erdenet require non-disruptive solar installations. Our L-Feet kits are anchored directly into steel purlins using self-drilling screws with heavy EPDM sealing washers, preventing vibration loosening caused by surrounding heavy machinery.
Cold storage roofs demand zero water leakage to protect internal insulation. The dual-seal L-Foot flashing design prevents ice dam condensation from entering roof penetrations during extreme temperature shifts between night and day in the Mongolian steppe.
For public sector rooftop solar retrofits in Orkhon Province, rapid installation and minimal structural weight are paramount. The high strength-to-weight ratio of AL6005-T5 aluminum L-Feet reduces load stress on older tin roof trusses.

Comprehensive field engineering answers for EPC buyers, solar installers, and structural consultants operating in cold climates and industrial regions like Erdenet.
Standard rubber washers degrade and crack when subjected to extreme freeze-thaw cycles. Our L-Feet kits utilize engineered EPDM gaskets specifically formulated with cold-climate plasticizers. These gaskets maintain flexibility and seal memory at temperatures ranging from -50°C to +120°C. Additionally, the stainless steel EPDM-bonded washer applies constant spring tension, keeping the mechanical seal airtight against trapezoidal tin sheets during thermal contraction.
We manufacture our L-Feet structural brackets using high-strength extruded AL6005-T5 aluminum alloy. AL6005-T5 offers significantly higher yield strength (≥ 240 MPa) and ultimate tensile strength (≥ 260 MPa) compared to AL6063-T5 (yield strength ~ 170 MPa). This higher structural capacity is essential for resisting intense steppe wind uplift and heavy snow accumulation on commercial tin roofs without increasing deadweight.
Yes. Xiamen Illumino Solar offers fully customizable L-Feet dimensions, including slotted height adjustments (typically 80mm to 150mm vertical slot range) to accommodate uneven tin roof surfaces. We also supply custom-length hanger bolts (M10/M12 x 200mm/250mm/300mm) designed for deep insulated metal sandwich panels or wood/steel purlin attachments.
All solar mounting products manufactured by Xiamen Illumino Solar comply with AS/NZS 1170.2, ISO 9001/14001, CE, TÜV Rheinland, and SGS material test standards. Our components come with a factory-backed 15-year structural quality warranty and a 25-year service life expectation, providing full financial bankability for solar project funding.
