Therefore, it provides a striking architectural contrast when paired with lighter building materials like glass, steel, or Neyriz White Marble.<\/p>\n<ul>\n<li>Deep black base color that remains consistent across large structural slabs.<\/li>\n<li>Minimal natural veining ensures a sleek, uncluttered industrial appearance.<\/li>\n<li>Rugged, split-face surface perfectly mimics natural raw mountain rock.<\/li>\n<\/ul>\n<h3>Surface Texture<\/h3>\n<p>The manufacturing process intentionally preserves a highly textured, uneven surface profile. Moreover, this three-dimensional face creates dynamic shadows depending on the surrounding lighting conditions.<\/p>\n<ul>\n<li>Cushion-like center protrusion adds significant physical depth to flat masonry walls.<\/li>\n<li>Rough texture completely eliminates unwanted light reflection and daytime glare.<\/li>\n<li>Tactile finish provides a robust, heavy-duty feel for premium projects.<\/li>\n<\/ul>\n<h2>Technical and Physical Specifications<\/h2>\n<table>\n<tbody>\n<tr>\n<td><strong>Specification<\/strong><\/td>\n<td><strong>Technical Value<\/strong><\/td>\n<\/tr>\n<tr>\n<td>Material Classification<\/td>\n<td>Metamorphic Limestone \/ Quasi-Granite<\/td>\n<\/tr>\n<tr>\n<td>Average Density<\/td>\n<td>2,650 &#8211; 2,750\u00a0kg\/m\u00a0\u00b3<\/td>\n<\/tr>\n<tr>\n<td>Compressive Strength<\/td>\n<td>110 &#8211; 130 MPa<\/td>\n<\/tr>\n<tr>\n<td>Water Absorption Rate<\/td>\n<td>&lt; 0.30%<\/td>\n<\/tr>\n<tr>\n<td>Standard Thickness<\/td>\n<td>2 to 5 cm (center cushion profile)<\/td>\n<\/tr>\n<tr>\n<td>Porosity Level<\/td>\n<td>Extremely Low<\/td>\n<\/tr>\n<tr>\n<td>Freeze-Thaw Resistance<\/td>\n<td>Highly Resistant<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>The table above illustrates why industry experts classify this material as a quasi-granite. Specifically, the high material density and remarkably low water absorption rate closely rival actual igneous rocks. Therefore, engineers can confidently deploy this material in severe freeze-thaw environments without worrying about long-term structural degradation.<\/p>\n<h2>Ideal Applications and Usage<\/h2>\n<h3>Exterior Projects<\/h3>\n<p>Contractors highly recommend this material for demanding outdoor environments due to its exceptional weather resistance. Additionally, its high compressive strength guarantees long-term stability in load-bearing structural applications.<\/p>\n<ul>\n<li>Building facades requiring a massive, imposing architectural presence.<\/li>\n<li>Retaining walls and exterior boundary fences in luxury commercial estates.<\/li>\n<li>Outdoor water features where strict low water absorption is mandatory.<\/li>\n<li>Landscaping elements and heavy-duty environmental retaining walls.<\/li>\n<\/ul>\n<h3>Interior Designs<\/h3>\n<p>Modern interior design frequently utilizes rugged textures to offset smooth, minimalist modern spaces. As a result, this stone serves as an excellent, highly durable focal point for interior accent walls.<\/p>\n<ul>\n<li>Lobby feature walls in upscale corporate office buildings.<\/li>\n<li>Fireplace surrounds demanding heat-resistant, heavy-duty natural materials.<\/li>\n<li>Interior commercial columns requiring permanent impact-resistant cladding.<\/li>\n<\/ul>\n<h2>Double Black Rock Face Processing Details<\/h2>\n<h3>The Rock Face Method<\/h3>\n<p>Factory technicians produce the Double Black Rock Face finish by expertly chipping the edges and face of the stone slab. Consequently, this advanced technique successfully replaces traditional pitch-faced stones by offering superior structural integrity and standardized dimensions. Furthermore, the resulting slab features a distinctive two to five-centimeter cushion right in the center.<\/p>\n<h3>Alternative Finish Options<\/h3>\n<p>While the rock stone finish remains highly requested, Pars Stone manufactures this quasi-granite in several other sophisticated surface textures. Therefore, procurement teams can precisely match the exact stone finish to their specific project requirements.<\/p>\n<ul>\n<li><strong>Brushed bush hammer<\/strong>creates a textured yet soft, leather-like tactile surface.<\/li>\n<li><strong>Groove process<\/strong>machines precise, linear channels directly into the slab for modern linear designs.<\/li>\n<li><strong>Ancient<\/strong>treatment artificially ages the surface to replicate centuries of natural environmental wear.<\/li>\n<li><strong>Brushed<\/strong>and sandblasted techniques shoot high-pressure abrasives to generate a uniformly matte, non-slip profile.<\/li>\n<\/ul>\n<h2>Installation and Maintenance Guidelines<\/h2>\n<h3>Substrate Preparation<\/h3>\n<p>Successful installation requires a thoroughly prepared, structurally sound substrate capable of supporting heavy masonry loads. Specifically, contractors must use high-performance, polymer-modified thin-set mortar to ensure permanent, void-free adhesion. Moreover, mechanical anchoring systems remain strictly recommended for exterior facade installations exceeding standard ground heights.<\/p>\n<h3>Sealing and Upkeep<\/h3>\n<p>Despite the naturally low water absorption rate, applying a premium penetrating stone sealer significantly extends the lifespan of the installation. Consequently, routine maintenance simply involves periodic washing with a dedicated neutral pH stone cleaner. Facility managers must strictly avoid acidic or abrasive chemical cleaners, as they will permanently damage the structural matrix over time.<\/p>\n<h2>Consult with Pars Stone<\/h2>\n<p>Pars Stone operates as the leading specialized reference for premium building stones in Isfahan, Iran.
