Lightweight truss made of materials that yield low thermal expansion and contraction. Average coefficient of thermal expansion minus 0.0428 part per million per degree Fahrenheit (0.0770 ppm/degree C) between minus 100 and plus 150 degree F (minus 73 and plus 66 degree C). Rotational distortion of truss less than 1/4 degree as temperature is varied through same range. High thermal conductivity minimizes temperature gradients, minimizing thermal distortions under variety of heating and cooling conditions. Elements of truss readily assembled.
