The Mounting Systems Universal ballast tray with a length of 1831 mm is a key component for the ballasted installation of photovoltaic systems on flat roofs. It is used to securely hold weighting materials (such as paving slabs or concrete blocks) when the static requirements for wind load securing exceed the substructure's own weight.Thanks to its universal design, it can be flexibly integrated into various flat roof systems from Mounting Systems. The generous length of 1831 mm allows the ballast to be distributed over a wide area, which minimises the point load on the roof structure whilst ensuring high stability at the same time.Highlights at a glanceHigh loading volume: Provides sufficient space for a large number of ballast blocks to guarantee maximum stability even in high wind load zones.Optimal load distribution: Thanks to its length of 1831 mm, the weight is transferred evenly into the base rails, protecting the roof covering.Weather-resistant material: Made of high-quality aluminium or galvanised steel (model-dependent) to provide long-lasting protection against corrosion.Universal compatibility: Suitable for different flat roof configurations, both for south and east-west orientations.Secure fixing: The tray shape prevents the ballast blocks from slipping or falling, even under strong vibrations or inclines.Easy system integration: The tray is screwed directly to the base or connecting rails, thus becoming an integral part of the structural system.Areas of applicationThe ballast tray is indispensable for penetration-free flat roof installations:Large-scale PV installations on industrial roofsSecuring large module areas against suction and pressure forces at wind speeds in accordance with DIN EN 1991 (Eurocode 1).Roofs with sensitive waterproofingWherever mechanical fixing (screwing) into the roof is prohibited for warranty reasons.Installations near the coast or in exposed locationsAdditional weighting option for systems exposed to extreme weather conditions.Installation & safety instructionsObserve static calculationThe exact amount of ballast (in kg) per tray must be specified in the project-specific structural analysis report.Protecting the roof coveringEnsure that sufficient protection mats are placed under the contact points of the tray or rails to avoid mechanical abrasion.Even loadingDistribute the stones evenly within the tray to prevent one-sided loading of the substructure. Properties  CategoryTechnical data: Universal ballast tray Length1831 mm System compatibilityMounting Systems FD3 / Universal MaterialSteel (galvanised) / aluminium Area of applicationFlat roof photovoltaic systems FunctionSecure accommodation of ballast weights AdvantageProtecting the roof waterproofing Weather resistanceVery high / corrosion-protected Installation typeHook-in / screwing on base rail  FAQs for the Universal Ballast Tray 1831 mmHow many paving slabs fit in one tray?Depending on the dimensions of the slabs.For standard paving slabs (40 x 40 cm or 50 x 50 cm), several dozen kilograms of ballast can be securely accommodated, depending on stacking and weight.Can the tray be retrofitted?Yes.Provided that the Mounting Systems rail system offers the corresponding mounting points, the tray can also be integrated during an extension or retrofit of the statics.Does the tray need its own drainage holes for rainwater?Usually integrated.The tray design usually provides for water to drain freely to prevent waterlogging and uncontrolled weight gain due to water accumulation.Is the mounting material for rail fixing included?Usually supplied separately.The ballast tray is usually supplied as an individual item. The required system screws and sliding blocks should be ordered in accordance with the parts list for the mounting system.

The Mounting Systems EW XL base rail with a length of 2287 mm is the load-bearing base element for aerodynamic flat roof mounting systems in east-west orientation (EW). The "XL" version is specially optimised for accommodating large-format solar modules (multi-cell modules), which have a greater width or length than standard modules.This rail is placed directly on the roof membrane (using building protection mats) and serves as a stable base for the front and rear module supports. Due to its precise manufacturing and integrated mounting points, it enables rapid, modular assembly of the entire rail system without roof penetration.Highlights at a glanceExtra-long (XL): With a length of 2287 mm, the rail offers ample space for modern, large surface PV modules and the necessary clearances for aerodynamics.High static rigidity: The special aluminium profile is designed for high mechanical loads, to safely absorb wind and snow loads.Tool-optimised: Features prefabricated slots and hole patterns that allow precise positioning of the module supports and connectors.Ballast-optimised: The geometry of the base rail allows for easy and secure placement of ballast stones to weigh down the system.Weather-resistant aluminium: Permanent protection against corrosion, even with standing moisture on flat roofs.System integrity: Perfectly matched to the EW components from Mounting Systems for a form-fit and stable connection.Areas of applicationThe XL base rail is the backbone for large-scale flat roof projects:East-west elevations (10°/15°)Coupling two modules "back to back" for optimal use of roof space with even energy production throughout the day.Industrial & commercial roofsUsed on bitumen, foil or gravel roofs, where a ballasted solution without damaging the roof membrane is required.Large format modulesEspecially for PV modules with a width over 1.10 m or other custom dimensions that require a longer base.Installation & safety instructionsBuilding protection mats (PADs)Always place suitable building protection mats beneath the base rail to protect the roof membrane from mechanical damage and plasticiser migration.AlignmentEnsure the base rails are aligned exactly parallel to each other to avoid tension in the module field and installation problems with the connectors.Ballasting according to staticsThe rail serves as a carrier for the ballast. The exact position and quantity of stones must be taken from the project-specific structural plan. Properties CategoryEW XL base rail Length2287 mm System compatibilityMounting Systems FD3 (East-West XL) MaterialAluminium (EN AW-6063 T66) Area of applicationFlat roof (elevation for large modules) FunctionBase profile / load bearing and connection WeightOptimised for low static roof load Weather resistanceVery high / corrosion-free MaintenanceMaintenance-free  FAQs on the EW XL 2287 mm base railWhy is the rail 2287 mm long?For double module structure.In an east-west system, two modules are mounted opposite to each other. The length of 2287 mm covers the base area of both modules, including the necessary clearances for ridge coupling and aerodynamic optimisation.Can I also use this rail for a purely south-facing orientation?Conditionally.Basically, this profile is perforated for Mounting Systems' EW system. For south-facing systems, there are often specific base rails with different lengths and hole patterns (e.g. S systems).How are the rails connected to each other?Via cross-connecting rails.The stability of the field is achieved by screwing the base rails to cross connectors. This creates a continuous grid that jointly absorbs wind loads.Is the aluminium walkable?Yes, during installation.The rail is stable enough to be carefully walked on during installation. Nevertheless, point loads directly on the roof membrane should be avoided.
