Designed primarily for outdoor, commercial and residential applications, BLACKline™hhp fence and railing products have good workability, high impact strength and excellent weather resistance. The compound is blended to obtain optimal impact strength and UV resistance, and the finished material has an excellent balance of properties for use in exterior applications under severe conditions.


All of BLACKline™hhp’s shop drawings were developed for the ease of integration of our products into most requirements needed for a variety of applications. Spacing of rails, pickets, and posts are critical to the strength of BLACKline™hhp’s products. Many of the drawings can be modified to adapt to commercial, residential, and industrial applications without compromising the integrity of the systems.
