Basic Gazebo Dimensions: The gazebo is 10 meters wide and 60 meters long. The column height is 3 meters, and the column spacing is 3 meters. The arch height of the curve is 1.2 meters. The entire gazebo is a standalone structure, not connected to any other buildings.

Construction Material Planning: The gazebo columns use 100mm diameter round tubes with a 3mm wall thickness. The upper chord of the beam uses 40mm diameter round tubes, the lower chord uses 60mm diameter round tubes, the vertical supports use 40mm diameter round tubes, and the diagonal bracing uses 32mm diameter round tubes. The top surface purlins use 40x60mm rectangular steel tubing, and the curved connecting pipes on the top surface use 20x40mm rectangular steel tubing.

Roofing Material: The roof uses attractive, hollow polycarbonate (PC) panels. PC panels offer excellent UV resistance for outdoor use and have a lifespan of 5-8 years. There's a wide variety of colors available. In this rendering design, we initially experimented with red and yellow but they didn't look good. The final decision was to use a lake blue color. A thickness of 10mm is crucial; thinner panels won't suffice, as the winds in Los Angeles are strong. Using lower-quality PC panels could result in the roofing being blown away.

Structural Key Points: What are these “top surface curved connecting pipes”? These are pipes that run along the vertical angle of the purlins. When the two PC panels are joined, the seam falls precisely onto this pipe, which is then covered with an aluminum strip and secured with self-tapping screws. This is a critical feature; the spacing must be 2.1 meters, as that's the width of the panel. The spacing of the roof purlins is generally 1.2 meters – too dense is wasteful, too sparse risks panel failure under wind pressure.

Foundation Style: Since this is considered a small building, a dedicated foundation isn't being used. Instead, holes are dug at the column locations, the columns are placed in the holes, positioned accurately, welded with anti-slip reinforcing bars, and then concrete is poured. The foundation pit is approximately 400x400mm deep, which should be sufficient to withstand the typical wind and snow loads in the Los Angeles area.

When constructing gazebos, shelters, or covered walkways in the Los Angeles area, it's essential to create a preliminary design plan, even for small projects. Avoid simply copying existing construction methods; every project has unique environmental factors. Relying on previous building practices might not be suitable for the new construction environment.
