Method of manufacturing a load structure

A method of manufacturing a load structure, the method comprising:

• forming a panel having a first side and a second side;
• clearing a fill passage through the panel, the fill passage extending from the first side to the second side;
• providing a tool having a first tool portion, a second tool portion, and a cavity disposed between the first tool portion and the second tool portion;
• providing a cylindrical member including a flange;
• disposing the panel within the cavity of the tool;
• disposing the cylindrical member within the fill passage of the panel;
• and
• injecting a coating through the cylindrical member and the fill passage such that one of the first side or the second side of the panel is at least partially covered with the coating, the cylindrical member is arranged with the flange within the fill passage to block the coating from contacting the other one of the first side or the second side.

• providing a tool having a first tool portion, a second tool portion, and a cavity disposed between the first tool portion and the second tool portion;
• providing a cylindrical member including a flange;
• locating the panel within the tool;
• locating the cylindrical member within the fill passage of the panel;
• injecting a material through the cylindrical member and the fill passage such that one of the first side or the second side of the panel is at least partially covered with the material;
• and
• blocking the material with the flange of the cylindrical member to prevent the material from contacting the other one of the first side or the second side of the panel.
