Deponti Giallo Aluminium Polycarbonate Veranda

System Overview: The Deponti Giallo is a heavy-duty aluminium veranda system designed for larger spans and robust commercial or domestic use. It is supplied as a complete kit including all structural profiles, selected roofing sheets, cover strips, and assembly hardware. (Note: Wall and floor fixings are not included as these depend on your specific substrate).

Key Dimensions & Profiles

• Back Wall Plate: 149mm height (Total height 185mm including the rounded profile cover cap).
• Front Gutter Profile: 166mm tall with a modern, leaning flat face profile.
• Support Posts: 115mm x 150mm Rectangular Profile (Extra heavy-duty). Supplied at 3000mm length for concreting in or cutting to size on site.

Ordering Widths Explained

The system uses "Centre-to-Centre" measurements for the roof beams, resulting in an "Overall Width" that is slightly wider than the nominal ordering size.

• Overall Width Calculation: The total width is the beam spacing + 60mm (30mm overhang from centre-line to outside edge on both sides).
• Example: A "5-metre" model has 5 x 1000mm beam sections + 60mm = 5060mm Overall Width.

Standard Finishes & Roofing

• Standard Colours: Traffic White (RAL 9016), Cream White (RAL 9001), Graphite Grey (RAL 7024), Jet Black (RAL 9005).
• Roofing Options (16mm Polycarbonate):
  • Standard: Clear or Opal.
  • Premium: Ultra Clear or Solar Control (Heat Reflective).

Post Requirements Matrix

Due to the massive strength of the Giallo gutter, the number of posts required varies depending on both the width and the projection depth. Please consult the table below to check how many posts your specific size requires.

Installation & Drainage

• Roof Pitch: Designed for a fixed slope of 157mm per metre (approx. 9 degrees). The wall plate height and front passage height are directly linked by this fixed angle.
• Rainwater System: Integrated internal drainage is standard. Water flows from the gutter down through the support posts.
  • Supplied with components for low-level discharge (out of the post bottom).
  • Drilling required on-site to position the outlet hole to suit your ground levels.

Coupled Systems

For installations wider than standard single units, verandas can be coupled together seamlessly. A support post is always required directly beneath the coupling point where two gutters join. (Note: Rainwater drainage cannot be routed through a coupling post).

Based on the official **Deponti Giallo Assembly Manual (Version EN – June 2025)** which you attached, I have rewritten the **Installation** tab content. I have verified the critical installation steps, including the specific **steel reinforcement strip** required for the gutter (Section 6.2.3 of the manual) and the unique two-part post assembly (U-profile + Click-on strip) which is different from other models. Here is the accurate, installation-ready content for your CMS. ```html

Installation Guide

The Deponti Giallo is a heavy-duty system designed for larger spans. While modular, its components are substantial (especially the steel-reinforced gutter), so we strongly recommend a minimum two-person team for safe lifting and positioning.

Key Installation Steps

The Giallo follows a unique assembly process compared to other Deponti models:

1. Wall Profile: Install first, ensuring it is perfectly level. (Fixings every 50cm).
2. Gutter Assembly (Crucial Step):
   • Before lifting, you must assemble the gutter on the ground.
   • Steel Reinforcement: Slide the provided 20x100mm steel strip into the gutter profile (use lubricant as per manual). This gives the Giallo its massive span capability.
   • Decorative Profile: Click and screw the front decorative face onto the gutter before lifting it into place.
3. Post Installation:
   • The Giallo posts are unique two-part units: a structural U-profile and a front "Click-on" cover strip.
   • Install the structural U-profiles first to support the gutter.
   • Only fit the front "Click-on" cover strip after the rainwater pipes have been connected inside the post.
4. Squaring & Beams: Install the two End Beams first to square the frame, then fill in with Middle Beams at 1000mm centres.
5. Roofing: Install polycarbonate sheets with the UV side facing UP.

Standard Dimensions Table

The table below shows the Maximum Factory Dimensions (based on standard 2500mm post height). Use this to check your site heights before cutting.

*Note: 6000mm beams are heavy-duty and may require additional local reinforcement depending on site usage.

Adjustability & Pitch

• Roof Pitch: The system is designed for a fixed slope of 157mm per metre. You cannot alter this angle.
• Height Adjustment: The front posts can be cut down to lower the front clearance.
  Important: If you lower the front height by 300mm, you MUST lower the wall plate height (H1) by exactly 300mm to maintain the correct roof pitch.

Ground Fixings

The Giallo requires substantial anchoring:

• Concrete Bases: We recommend sinking the structural U-profiles into concrete footings for maximum stability.
• Drainage: Rainwater pipes run inside the U-profile. Ensure your concrete base has a drainage outlet or soakaway connection ready before pouring.

For full terms and conditions, or to initiate a claim, please contact our customer service team with your original proof of purchase.

Accurate measuring is essential for a successful installation. The Deponti Giallo uses a fixed triangular geometry: the projection length and the roof pitch determine your required wall height.

1. Optimum Installation Height & Future Proofing

There are two key reasons for reducing the height from the factory maximum:

• Future Enclosures (Glass Rooms): The Giallo is a popular model for creating enclosed glass outdoor rooms. Standard sliding glass doors typically operate between 2100mm and 2200mm. Installing at the full 2500mm height would leave a large gap above the doors, requiring expensive additional fixed glass wedges.
• Aesthetics: A height of 2100mm–2200mm aligns with standard internal doorway heights, creating a seamless flow from house to garden rather than a "looming" high canopy.

2. The "Golden Rule" of Roof Pitch

The manual strictly specifies a slope of 157mm for every 1 metre of projection to ensure watertightness and stability.

Crucial: Because the roof sheets and beams are rigid, you cannot change this angle. If you cut the front posts to the recommended 2100mm-2200mm height, you MUST lower the wall plate by the exact same amount.

3. Standard Dimensions Table

The table below shows the Maximum Factory Dimensions (based on a standard 2500mm clearance). Use this as your starting point for calculations.

4. Calculation Example

How to calculate for a "Future Proof" height of 2200mm:

1. Decide your desired front height (e.g., 2200mm).
2. Calculate the difference from the factory H2 height (2500mm - 2200mm = 300mm difference).
3. Subtract this 300mm difference from the Factory Wall Height (H1) in the table above.

5. Checking for Obstructions

Before finalising your height, check the wall for:

• Outward Opening Doors: Ensure bi-fold or French doors can still open fully under the chosen roof height.
• Wall Obstacles: Check for soil pipes, gas flues, or security lights that might clash with the wall plate position.
